Help: Logickeyboard german, Win7 german, PT english -> wrong shortcuts

[joachim]

Help needed from a german PT user with german Windows 7 and Logickeyboard with german layout; I am clueless !

PT Preferences :
Automatically switch Input Language : checked
Language : English

But :
“Ö” does not do „Move Edit Selection down“ , it does : „Cycle through Edit Modes“
but : "Ö" types correctly "Ö" when entering text (clip name renaming, ...)

“Ü” does not do „Play Edit Selection“ , it does : „Move Edit Selection down“
but : "Ü" types correctly "Ü" when entering text (clip name renaming, ...)

“?ß” does not do “Track View Toggle” , it does : playback

“*+” does not do „Play TL Selection“ , it does unknown/nothing

“Z” does not do „Snap Start to TC“ , it does : „Undo“

“Y” does not do „ Undo “ , it does : „Move Clip Start to Play Time“

“-_ “does not do „ Move next large Nudge Value forward “ , it does : „Track View Toggle“

Win 7 : English

Win 7 : English

Always after quitting PT and rebooting PC.
Nothing works :
"Ö" types "Ö" , but the shortcut does not work
or
"Ö" types ";" and the shortcut works.

That is a Hexenprobe, no idea for a solution.
Is there some other Windows setting, that I miss ?

I would be very thankful for help,
Joachim
