Hi Dave, it's possible to have problems like this if your video driver has forced anti-aliasing to be turned on.

MoI uses the video card during one portion of the selection process, and if it anti-aliases the selection data it messes it up.

MoI requests to not have anti-aliasing for this process but some video cards will do it anyway if you have adjusted their driver settings to have it turned on automatically.

So please take a look at your video driver settings - if anti-aliasing is turned on automatically there for all programs, you can set up an exception for MoI.exe to have it "application controlled" instead of forced on, and that will likely solve the problem.

Please let me know if you still see the same problem after adjusting that.
