Hi Marv, yes like Pilou writes above it's likely to be a video driver problem.

Do you possibly have an Intel video driver for that machine? If so, then try the following:

Go to Options > General and push the "Edit .ini file" button there.

Inside moi.ini find the line that says:

DisplayThreadLimit=

and edit it to say =1 at the end, like this:

DisplayThreadLimit=1

Then save that and close notepad and start up MoI again, does it behave better for you now?

Since MoI v3 MoI by default will use multiple cores in the display engine to speed things up, but the Intel video driver does not seem to get along with that and it seems to have gotten more cranky about it in recent versions as well...

Hope that will help stabilize things for you.
