Google is your friend.  WS_EX_TOOLWINDOW is used to create floating 
toolbars, which can exist outside of the parent app.  You don't want 
those showing up as main windows.  WS_EX_CONTROLPARENT essentially says 
"this window contains other controls".  Getting rid of this probably 
gets rid of text-only windows, like tooltips and balloon help.

The "spyxx.exe" tool can be used to poke around the window list to find 
these things.
