Using the "Run Command" dialog in KDE, checking file permissions, and other
similar messages are hidden under other windows permanently when using xfwm4 in
KDE.  I would be willing to write a patch for this if someone can help with the
diagnosis.  It seems like some NETWM window hint is not being followed properly.

Reproducible: Always
Steps to Reproduce:
1. right click on a file on the desktop/in konqueror and click "properties"

or ...

1. press alt+f2 (or your 'run program' modifier)
Actual Results:  
Window comes up behind other windows, but has focus.

Expected Results:  
Window should come up on top of all windows and grab focus.

Some output from 'xprop' on two windows displaying this behavior:

A "file properties" window:
