Hi xrok1 - how complex is the file you are using?

The screen going black is probably some side-effect of Vista's new display manager, it can tend to cause some quirks like this. I've done some work to try and reduce some side effects in some situations, but some things probably will need to be solved by Microsoft.

You may be able to reduce the black screen display by turning off the "Aero" display and switching the desktop theme to "Windows Vista Basic" instead. Or another option is to right-click on MoI.exe and pick Properties / Compatibility tab / check the "Disable desktop composition" option. That will disable Vista's display manager thing just while MoI is running.

Does that make any difference with stuff not turning black at least?

I would think that this would happen more often on file saving than on booleans - there is some work I can do in v2 to reduce this for file saving but for now you just have to wait for it to finish.
