Only standard modules AFAIK. Maybe I should try installing on my desktop to see if I can narrow the problems down to my laptop (which is MacBook 2.4 GHz Intel Core 2 Duo, 4 GB RAM BTW, - rather old as you see which might or might not have something to do with it...). The window issue is stable and occurs every time I open several images, no exception. The other two issues are more random, if anything they seem to be happening when moving windows around, sometimes the app feels a bit sluggish and moving an icon can actually cause it to get stuck to the cursor (hehe, kind of cute) as if it missed you actually releasing the mousebutton. I know this issue has been followed by a crash, - and I am pretty sure it was a Segmentation Violation message. I'll keep checking to see if I can detect a pattern.
Would I be able to install PI on my desktop for testing?
Best regards,
