--- Comment #2 from bailey937@yahoo.com 2012-01-30 15:55:23 CST --- Created attachment 38609 --> http://bugs.winehq.org/attachment.cgi?id=38609 program for reproducing bug 29748
Here is a simple win32 program with source that reproduces the bug.
See README_fstest.txt for a description of how to use it.
In short, if you run it and then left click in the main window, it will create a fullscreen black window. If you right click in the full screen black window, it will hide the fullscreen black window. At that point, the mouse should not work if you click on other X windows.
I've verified that it causes the problem on my computer (Ubuntu 11.10) with Unity 3D and also with Lubuntu (my normal environment).
