Otto:
Found the problem. V2 can remember the “Recent Folders”. If you had a Removable memory “E” plugged in and later removed the V2 would look for it, but it is no longer present… After disabling the option for displaying the Recent Folders V2 starts working properly.
...
Just noticed that "E" is my CD drive where no disk is present.
