When EnableWindow disabling a window in Wine, mouse capture in its child window
gets lost. As far as I tested in windows, capture is released only when
disabling the exact captured window, rather than its parent window.

There's a tool named 'Spy32' ( download at
http://www.woodmann.com/RCE-CD-SITES/Protools/files/utilities/spy.zip ), please
try picking window by dragging the 'target' icon to target window, it will
misbehave like the mouse button never released. In further debug info (
attached ) I saw it disable its main window to avoid picking itself, it indeed
plans to re-enable the window when mouse button is up but it dose not as
capture has been released and no WM_LBUTTONUP is received.
