I know; I feel your pain. This has happened ever since I upgraded to Win7 64-bit (2 years ago now). My guess is it's an interupt conflict. I have a particular email scanner (scans my 4 email accounts and notifies me if I get a new message) and when in blinks (which I can't see since it minimizes in my tray) I get a better chance for GIMP to crash. I've posted several times in several forums. Even tried running GIMP in compatibility mode but to no avail. I just save frequently. I'm hoping that 2.8 64-bit (going to probably go complete 64-bit with this version of GiMP keeping 2.6x around for the plugins that I need to have that has no 64-bit compile) eliminates this problem. I have fiddled with the various 2.7x 64-bit builds of GIMP (but not much) and will add that this freeze/crash issue has not occurred with this build of GIMP. Even though GIMP would sometimes crash when I was using XP, it didn't do so at the frequencey that Win7 has and I bet the XP users here have really not experienced this issue and only folks that have can simpithize with you. Again, let's just hope when GIMP 2.8x gets released, all problems like this will go away.
