This just recently started happening. AE will not preview the text on the main screen, however I can see the text in the Effects box. The type is white and the background black. I've updated the software, and restarted everything, I've even done a reinstall. Help??
Thank you! I had to change my fast preview settings. I chose OpenGL Active instead of Wired Frame. Although, I'll have to play around with it because I got an error message last night that said it caused the program to crash.
Just turn OpenGL off, then. You won't miss it.
