[visionegg] Re: _imagingtk error

Hi, andrew, 

All I really need the GUI functions are for popping up a dialog box for user
responses, doesn't necessarily have to be a GUI object.  

Anyone have suggestions for libraries or code snippets for performing these
kinds of functions (preferrably NOT GUI-related, as this seems to bloat the code
substantially)? Example: for one study I wrote in C, the library we were using
only allowed dialog boxes to pop up on the second screen (the experimenter
screen, not the stimulus screen), so I had to write my own text dialog routines
for use on the stimulus screen.  Shouldn't be too hard to port, but maybe
someone's already got some code that will take care of this in python.

In any case, I'll check with the pygame folks to see if they know what's going
on... 

cheers,

Hi Gabriel,

I don't have the time to delve into this right now, but I think it's 
more likely a pygame issue -- the error message indicates something 
about threads. AFAIK PIL doesn't use threads, but I think some of the 
Mac OS X specific bits of pygame might.  (The Vision Egg itself does not.)

Early next week I can take a look if you're still stumped...

Cheers!
Andrew
