Once again, it would seem someone didn't read the first post.
Right now, wine handles desktop switches by an artificial sequence of
minimize/restore. It's not the minimize part that's the problem, it's
Now that I think about it, it might just be that 'SetActiveWindow(hwnd)'
I mean, the problem is that upon getting back to the desktop with the
window, the window shouldn't be automatically be given focus if the wm
doesn't do it.
In the patch I'm skipping minimize step to avoid restoration, but that
makes the windows treated by both 'can_activate_window' statics as valid
targets for events while being invisible. I'm just using WS_DISABLED to
...if it's actually just that SetActiveWindow that's the problem, a
cleaner solution would be possible, but I'm not sure how SC_RESTORE
