I have noticed that on multiple occasions I have accidently opened up a idea project multiple times with IJ 13.
I believe this happens because I have double clicked on the project selection screen when IJ starts up.
This is hard to replicated on demand but I have done this at least 3 times over the last month.
Can this result in corrupted project files/caches ?
I am starting IJ 13 using idea.exe on a 64 Bit Windows 7 machine.
