Hello there!
I've run into a serious issue with my OpenGL 3D window. It's hit and miss, more often hit and not miss though. I load up my project and often desire to work on the building in 3D model space. When in the 3D window I'll either use the 'fly' tool or simple navigation. After moving throughout without any hitches and come to a stop the window goes BLACK! I'm still able to manipulate objects and the model while the screen is in this state. Grrr...
I've un-installed and re-installed my ATI video card drivers twice, checked for any Windows OpenGL updates...the symptoms persist. I've narrowed the problem down to OpenGL for this doesn't occur when utilizing the Internal Engine for 3D or within any other window (floor plans, sections, etc.).
Any suggestions would be greatly appreciated!!
