Ok, the problem is solved..
The reason for the problem is simple..
Its not about quickmessage or quickcommands...
But i'm using menu files to check the FPS of a player.
To get it working i open it again and again..^^
If i remove this FPS check its working fine! :P
But now i have to get a new way to check the FPS for my custom hud... :'(
Thank you all <3
