I'm trying out V4 and V5 to see if I can see any differences as a new user. he first ting I saw was setting opengl was messay. The screens turned all dark and I had to turn off Enable background Draw Thread. Because when I moved the camera in the top view, it looked like it just made a copy and not moved it. When in fact, it just did not delete the old picture of the camera. Also, I noticed that when you created a terrain and applied a texture to it in the camera window, the terrain was still dark grey. V5 shows it as green (texture). Is this a setting in 4 that I don't know about? And the documentation that comes with the demo is not very good. I would have included more documentation to get the trial user hooked into buying it. Comments?
