Hello,
I'm not 100% sure this is right, just because a window has WS_CLIPSIBLINGS and WS_CLIPCHILDREN does not mean we necessarily want to manage it.
For example, both Trillian and WinAmp set this combination, and these need to be unmanaged (ideally semi managed I think, where we draw the system bar, let the app clip it away, then hand over to the window manager setting hints for no decoration.. but thats another matter)
I don't know even what means "WS_CLIPSIBLINGS" and "WS_CLIPCHILDREN" ;) I have been searching a way to install this applications, using managed mode O:-)
Regards, Carlos.
