ok i fixed it
graal doesn't crash randomly nor does it crash when i open PMs.
go to compatibility and run in Windows XP (SP2) mode and check the box for "Disable display scaling on high DPI settings" :edit: AND "Disable Visual Theme"
btw my pc specs:
AMD Athlon 64 Processor XP 3500+
2047 MB RAM
32-bit OS (VISTA)
NVIDIA GeForce 7300 GS (with latest nvidia drivers)
graal finally works! yay!
