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.
