X window error

[lostson]

I have recently installed qlwm and have been using it day to day. A problem I have noticed is that when i run qdesigner and create a new project I cannot drag the widgets from the left to the new project they just dont show up.
When starting qtdesigner from a terminal window i get this

designer-qt4 
X Error: BadWindow (invalid Window parameter) 3
  Major opcode: 20 (X_GetProperty)
  Resource id:  0x1a00003

designer-qt4 
X Error: BadWindow (invalid Window parameter) 3
  Major opcode: 20 (X_GetProperty)
  Resource id:  0x1a00003

I would like to fix this problem either with qlwm or designer if there is a way to. I would like to continue to use qlwm. It gets kind of tiring switching to another desktop just to use qtdesigner, thanks ahead of time.

The strange thing is is that qdesigner works on all the WM/DE's that I use it is only with qlwm that i have this problem.
