I’ve seen this question asked a few times, but, with no definitive answer. Does anyone know how to manage OpenGL in an MDI application that has a dynamic splitter? I have it set up so that each view in the splitter has its own RC, and, I call wglMakeCurrent BEFORE drawing (in OnDraw). Yet, OpenGL does not always update the view(s). It appears to be tied to the view that is “active”. Any ideas?
