Guest is Window7, 32-bit, 2D/3D acceleration enabled, 128MBytes of video memory, 2GBytes of memory assigned to the machine, both 1 and 2 processors assigned to the guest. I have tried all the things I could think of, changing the assigned memory, changing the video memory. When I enable OpenGL in my Cadence Allegro PCB program, and click on a drop down menu, the screen doesn't refresh after the menu goes away. If I enable the infinite cursor, it is invisible. I tried both the v3.1 and today's update of v3.1.2. Everything works fine on a Windows XP Pro virtual machine." defect closed 3D support VirtualBox 3.1.2 fixed screen refresh Windows Linux
