Icon handling and formats changed a bit with WinXP, due to addition of 
Alpha support. I made some changes in winmultiwindowicons.c. It was 
trying to change window icons by changing the class icon, which (in my 
experience) does not update the windows of that class. A better method 
is to directly change window icons with WM_SETICON messages.

The current design is to make a new Window clas for every window. I 
don't think this helps anything. I think the way to go is to make a 
single window class for all X-managed windows, with the class icons 
defined as the X logo. If one-class-per-window was done just for icons, 
it doesn't work anyhow. Does anyone know of any reason not to use just 
one class?
