I've sent 2 patches addressing this issue to wine-devel last year. The first 
patch(http://www.winehq.org/pipermail/wine-patches/2005-March/016558.html) 
made children of the desktop managed, the other patch made WM_SYSMENU(Sorry, 
can't find this one in the archives) windows managed. Both patches were 
neighter applied nor discussed further.

My observation was that all affected windows have a WM_SYSMENU | WM_POPUP 
style, but do not set WM_CAPTION | WM_EX_APPWINDOW or any other styles which 
would make them managed. Making WM_SYSMENU windows managed fixed a few apps, 
like Steam, Quicktime Half-life(parts not managed, can't navigate through the 
menus). I didn't notice any side effects(The windows had no decoration, which 
is completely correct), except that Steam and QuickTime seem to provide their 
own window movement code which conflicts with KDEs window movement handling. 
So if you move a Steam window to the corner of the screen, it won't move out 
of the screen, but Steam expects it to and mouse clicks are placed 
incorrectly. Quicktime can't be moved at all. I am not sure if this the 
direct fault of making those windows managed, or if there are some other 
bugs.
