The haptek player which generates the 3d characters is an annoying little application. I was considering using the haptek characters for an astronomy program with local schools, during testing, I found on avaerage 40% of the computers I tried to play the characters on froze. The haptek player fights other applications that are cpu intensive. I found that on most of the systems, it was seti at home running in the background that conflicted with the player. On some systems, it was the brand of virus software being used, and the remaining systems it was other applications running in the background from the sys tray.
You can't forget though, that if your graghics card does not support video acceleration, the player will freeze as well.
I hope this helps
