Hi again,
I set up in my config a q key for cuein+, w for cuein-, e for cue set etc, etc. Let’s go for example in a properties dialog, in some edit box. I am not able to use this letters. I understand, they are a reserved for mairlist, but could you Torben reserve it only for situations, when they are necessary? For example keys to set a cue, mix, ramp points only for pfl tab, tag and this places in mairlist, when program displays assigned buttons? Because I am not setting a mix points in main window, and i am not operating a players decks in a pfl window. 
Am I right?
All PFL-related hotkeys (i.e., the commands starting with “PFL …”) should only be enabled while at least one PFL window is active. When the PFL window is closed again, the hotkeys are released until you open another PFL window.
If you still think you have found a bug, please send me your mAirList.ini.
Window, you said… Hm, in a properties dialog box, is a pfl tab, so it should be a reason. I checked this, and a situation is:
First time, when i try type sth in edit box in propperties, all is ok. But, when I active a PFL, the assigned letters are locked, even when i close a window, and reopen it again.
Sorry, I cannot reproduce this, even with the mAirList.ini file you sent me. After I close PFL and open a new properties dialog, I can use the keys again for typing.
Which Windows version do you use?
