Installed program, reinstalled Dark Elegance theme, and reset to my favorite Layout. The program had worked fine up until today (approximately 4 days) when it began hanging and restarting upon right-clicking any file type or folder. Not sure what is going on.
The problem seems to have been WinRAR. After updating NotePad++, blocking TI extensions, and disabling NOD32's context menu; the problem was still there. I uninstalled WinRAR, rebooted, then set DO12 as the default zip handler. Then all is well.
