I have found some problems running Allegro programs in ReactOS. When I
have tested it they started up and the mouse moves the upper right hand
corner of the screen and ReactOS apparently hangs. I'm curious why is
this happening; although, I think it is possibly some bugs (or bug) that
is causing it, or it is caused by an unimplemented feature. It is most
like located in the DirectX and OpenGL components. This realtes to bug
1112.
