1.) The bug is now fixed (new build tested).
2.) "Devices" tab: Now it is clear for me.
The problem was, my column wwwwiiiiddddtttthhhh. ; )
The folder symbol to browse the files was not visible (far right)
So I was wondering, how I can load/mount any software.
Adjusted now the column width.
Thanks for your patience.
Danke f�r Deine Geduld.

Suggestion: If I�m in the device setup window and press the right mouse button a popup menu with "Open ..." or folder symbol should be visible. Thus, it is always available.
So we can prevent this kind of problem if a user have a wrong column width or may a low screen resolution.
PS: The last selected software (File) should be automatically saved ( or as option in the settings) before you quit QMC2.
Because if I restart QMC2 the file field is empty.
