All of which has set me re-looking at a problem we've had here for some time
which is sort of the reverse of the problem you have. I have an application
that when run within a published desktop provides two buttons on the taskbar
(within the published desktop). I believe it is Delphi based, and if I switch
between the two butons the application just freezes so it is an annoyance. If I
publish it as a seamless application it appears to behave itself with a single
button on the task bar. Have just tried an RDP desktop and still get the same
two buttons, so clearly not an ICA issue. Any ideas where to start?

Hello Shane,
I have gone through a similar issue with an application that worked under XP
Fr3 + Post Sp3 Hotfixes but then changed once we upgraded to FR3 SP4 and still
occurs in our PS4 test Farm.
We were also able to mimic the issue via an RDP session thus actually proving
it wasn't a pure Citrix issue but rather the programmer not using parent and
child windows properly.
On a test server we changed the RDP listener settings so that the application
would start whenever we connected via an RDP session. This is about as close as
you can get to seamless apps with RDP.
We then found that the application behaved exactly the same as a seamless ICA
session and one icon would minimise to the corner of one screen rather than the
taskbar.
Have you tried this with RDP sessions to compare ?
There does appear to have been a heck of a lot of undocumented changes to the
seamless engine since XE103W2K133 (a private hotfix). Our issues did not occur
with XE103W2K126 or lower. We got the same issue without any hotfixes on PS4
new hotfixes didn't address the issue. The seamless code does appear to have
been tightened/altered with XP FR3 SP4 and PS4.
Also don't forget you can alter the behaviour of your seamless applications
without affecting other applications.
Have a look at the following urls
http://www.brianmadden.com/attachments/seamless-flags-extended.pdf This PDF is
excellent (thanks Thomas!) and provides a ton of information in one place.
These two Citrix articles provide additional information.

http://ctxex10.citrix.com/kb/entry.jspa?externalID=CTX101644
Don't forget that if you use SPY++ on a seamless application rather than on a
desktop, you have to publish SPY++ on the same server and run it from the same
server ( i.e. session share).
Use SPY++ to identify the windows classname and using the information above it
is pretty easy to create registry entries to alter the behaviour of your
seamless apps. Typically unless your application has a known issue with
seamless apps, start with the lowest values and work your way up until the
behaviour is altered. If nothing happens try looking at the various seamless
app tweaks at the back of the PDF to see if any of those alter your seamless
behaviour.
You don't have to restart your server each time you make a reg change. Just
make sure you close your seamless sessions and restart them.
Id love to know how you get on. I've spent loads of time with SPY++ and its
immensely satisfying when you get the right registry entries. Bl**dy annoying
getting to the fix though :¬)

Thanks Greg - we are not running Win2k3 SP1 yet, so that may be a good
place to start to see if the behaviour "goes away" - that is the only
difference I can see - our version of Ellipse is the same, PSE version is the
same with no other obvious differences. I will do some testing and then let
you know how I go - thanks again for the feedback.
Cheers,
Shane

we are running PS4 on Win2k3 SP1 with all available updates installed
from MS.
Under TWI, i have not added anything special. All that is there is the
DllName and NotifyEvent keys
I have PSE400WK3003 installed. that was for printing though. I'm
running ICA 9.1 as the client and we are running Ellipse 5.2.3.2

hmmmm.....are you able to check the registry on your box to see
if you have any special entries under the
HKLM/System/CurrentControlSet/Control/Citrix/wfshell/TWI area for seamless
flags etc. Also, what OS + Patch level are you running it on, what version of
Ellipse client & do you have any Presentation Server 4 hotfixes applied ?? Any
further info appreciated.
Cheers,
Shane

I just tried it both ways. what i am seeing is a momentary
flash of a second icon in the systray when opening other files. there will be
two then one goes away almost immediately.

Thanks Greg - it is reverse for us - it behaves fine
when run locally from full Citrix desktop - but misbehaves when run via
seamless app. I look forward to your findings....

let me see what I can figure out. we have been running
Ellipse here for a few weeks on PS4 and testing for a few months before that.
I have seen it happen in a full dekstop but not in seamless sessions.

Yup - Ellipse is the culprit - 2 taskbar icons
appearing for every MSQ executeable that is run (consistently) - this wasn't a
problem prior to Presentation Server 4.

you get this running Ellipse? I have seen two
tray icons appear at times. How many are you seeing?

Hi All - we have an in-house ERP
application which we publish seamlessly
via Citrix Presentation Server 4. The
application has a number of
independent executeables which the user
can invoke from within the
application. Each executable then
displays a new window for the
associated exe. The app behaved fine
when published as a seamless app,
until a recent Citrix upgrade from XPe
to Presentation Server 4
Enterprise. Now when the independent
executables are invoked, we end up
with 2 task bar icons for every exe
that is run (only one of the task bar
icons can be set to focus though - if
the other is clicked, it
automatically toggles straight back to
the existing one with focus). The
executables are written in
borland/delphi, which do have some known
possible issues with seamless mode, due
to an "invisible" window which is
generated for each exe. I have tried
numerous seamless flag registry
tweaks documented by Citrix + Brian
Madden that relate to strange seamless
apps behaviour - however no resolution
as yet. Any help with this one
would be appreciated.
