Phew, thats pretty tough.

Are there differences in installed programs? TweakUI or similar might be 
candidates which change expected windows behaviour. If such programs
are installed, please check if the settings of the programs differ.  

If this does not give any clues there is the possibility to compile 
XWin with massive debugging output. It will print which windows messages
are received and how they are processed. I can provide the binaries in 
the next days.
