What causes the warnings
TIFF files contain tags (that is what the T stands for). No one
understands or knows what every single tag represents. The warnings tell
you that a tag which is not understood has been seen.
Usually this will do no harm.
-- is this expected behaviour with TIFF files?
Yes.
I find I can save the pictures (line art) out of OPW as Draw files and
get round the "warnings" problem, but the files are just as big (if not
bigger) as the original TIFFs.
As expected. When you drop a TIFF file into a frame it is converted into
a sprite in a Draw file.
1GB physical, 1535 MB virtual (set by Win XP) -- should I increase it?
And if so, by how much?
Sounds like plenty. It really depends what else you want to run at the
same time as OP.
From what you say below, if I increase it to 3GB, as things stand OPW
will only be able to use up to 2GB (?)
Is there a website that explains how to do this?
http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx
In an ideal world, perhaps ... But does it do what it says on the box?
32-bit Windows is supposed to address 4GB of physical memory and my
motherboard has a capacity of 3GB, but if I install more than 1GB the
whole system collapses :(
32 bits gives you a 4GB address space. Usually this is split 2GB for
Windows and 2GB for the application.
By setting a switch when Windows boots you can change this to 1GB for
Windows (with potentially a performance hit) and 3GB for apps.
This is address space. Actual memory is another matter.
There is another question, Windows does not allow any old app. to access
3GB because (shades of RISC OS) many don't like "negative addresses"
i.e. addresses which have the top bit (bit 31) set.
I don't know at this instant if I have built OP with the necessary flags
that tell Windows that it is 32 bit safe.
XP 64 does give you a much bigger address space. Presumably one day
everyone (and everything) will move to 64 bits. However so far I've only
done a 64 bit version of DPScan - and with no evidence that anyone has
used it, I'm not in a hurry to undertake the conversion of OPW.
