Hello,
I should have clarified. Was using the UFO-AI 2.3 as revisions progressed, mouse functions is working normal.
Later, I came back on and discovered 2.3 was released as stable, this is where the problem occurred. therefore has nothing to do with how old driver/video card is.
In fact because of other game i was playing on, I updated the drivers. and is OpenGL 2.0 compliant.
