for those of you having this crash - do you have unlocker installed?
i ask, because fp discovered if this program was running, the crash happened, i was also able to reproduce this (picking 12+ files seems to do it), it would appear that the program is using setwindowshook to set hooks, im not sure exactly what its doing, but somehow it interferes with pid, possibly it subclasses something, and destroys data pid uses..
for me, the problem is caused by this program, as if you uninstall it pid is perfectly fine, so i think we might have to contact the author about this (unless i can find a workaround - but that doesnt look so simple)..
if you are not using that program and still get the crash, i might need you to run some beta exe's for me
NOTE : this is not related to the running pid -> crash, its related to scanning files from the context menu...
