Hi phlatt5th, the full screen script shouldn't really have any effect like that, it's maybe more likely that there's something going wrong with your video driver.

Have you rebooted your system anytime recently? If not that's probably a good thing to try first.

Also is it particularly hot where you are at? Is it possible that your system is getting overheated?

Mike and Michael thanks for the quick responses. @ Mike the view-port was acting up with or without any objects. Michael my graphics card is up to date, all other 3D apps were running well. My little traveling work box is getting on in years though not quite ready to part ways ;) However, I uninstalled Moi brought in a fresh copy ran it with no rotation issues carefully put back all my scripts including full screen. Hiccups gone, Back in business No issues currently!!
A day without Moi is just not acceptable LOL
Thanks again.
Cheers.
