Hi Jason, Robert I have tested 2.6 where it still seems to be a problem.
There is no hurry with this, but it would be really nice to make sure that the problem is with the graphics card.. I'll probably try to build on WindowsXP64 later this week and see what happens, don't have the environment setup so that might take a few days. Robert, do you see any problem with the code i supplied? It seems that the behavior in my end is consistent. Everything works fine as long as you don't open any new windows after any has been closed. The reason for my initial suspection of GraphicsContext was mainly of the method GraphicsContext::getOrCreateCompileContext() I figured that when creating window1 it would get ContextID=1. Window2 would get ContextID=2. When closing Window1 the context would be released/freed or something. Then, when creating window3 it would reuse ContextID=1 which is dirty and unusable. Creating Window4 would get ContextID=3 (since 1 & 2 is in use) and work fine. However, this is just a very far fetched guess ( i have no idea whats going on behind the scenes). And i cant debug the code, haven't figured out how to get the .cpp files in eclipse without it building them.
