I made a OpenGL program in Delphi 4 that crashes sometimes when swapping the buffers. When I run the program outside of Delphi or inside Delphi but with Integrated Debugging off everything goes fine, but when running inside Delphi environment with Integrated Debugging checked (default) the program sometimes crashes, and Delphi shows where the crash happenned: GDI32.GetObjectType. Does anyone know how to fix that?
