SYMPTOMS

Opening any menu of a program created in the 16-bit edition of Visual Basic, version 4.0, containing the 16-bit OCX controls listed below or any control using the 16-bit edition of the Microsoft OLE Control Developer's Kit (CDK) shipping with Microsoft Visual C++ for Windows, version 1.5x stops the system from painting to the screen when running Microsoft Windows for Workgroup version 3.11. Any programs running in the background in addition to the Visual Basic program still run, however, the screens of these background programs are not repainted. Clicking near the menu to close the menu resumes screen painting. This behavior only occurs when running Windows for Workgroups 3.11 and is limited to the following controls: 
   Custom Control Name                    File Name
   ---------------------------------------------------

   Desaware Animated Button Control      ANIBTN16.OCX
   MicroHelp Key State Control           KEYSTA16.OCX

   Pinnacle-BPS Graph Control            GRAPH16.OCX
   Sheridan 3D Controls                  THREED16.OCX
