I've just installed the latest build of IDE5.2 and it still crashes as soon as I boot it up. I have to reboot my computer (AMD64) before I can try it again because once it's crashed, it won't restart,
Actually, it is still showing as running in the system monitor, but the program is invisible. If I kill the process I can restart Komodo, but as soon as I try to open a file it crashes again.

Any ideas??
