Hi pafurijaz,

Are there any settings for the graphics card driver about forcing anti-aliasing on? One problem that can cause this symptom is if the driver does antialiasing even if MoI has not requested it, it messes up object id information.

If there is a setting for "application controlled" antialiasing rather than forcing it on, try that.
