Try reseting your video card options (if you have changed them in the past) as well as updating your driver (which I am guessing you already have done).
I am not getting any of the problems you speak off and I been using MoI a lot lately trying to finish this project. I am runing on Windows XP SP2 with an Intel R Extreme Graphics Card Chipset (Integrated crappy) has 32MB of memory.

On a chat with dell now, and downloaded a newer driver (Trying to rule everything out)

Ill give it a shot with the newer driver. I also think I still have the NOV version too and Ill test it with that

Thanks for the suggestion Val. This machine is pretty solid hence my confusion? Ill see if i can get it sorted (4 hours into it already sheesh!)

Still I love the program! Just want this bad boy to work on my machine :)

Thanks for all your testing Costas.

If the Nov one does work (with your current system), then I can start sending you some custom builds that have one change applied at a time, to try and narrow down what particular thing is causing the problem.

So far I have been whacking the Dec ver with the latest nvidia update, insane sweeps, rotation after rotation, moving it all over the screen, with no freezing issues or hiccups. (about twenty minutes so far) so Im hoping that this may have solved it.

I did however keep the setting in the ini file as "n"

Im trying to cram in as much UAT / test case scenarios as possible. :)
