Hi Jsilvers,
While waiting to have someone respond, you are going to need to post your hardware specs, and version of FSOne, and if you have installed all the patches and if you have upgraded sound and graphics drivers to thier latest versions. I don't know the answer, but have seen a lot of questions and these are always asked, might as well save a few hours and post'em now.
One quesion I might ask is if you have the stock curser selected in windows, or a custom curser or even a custom theme. If so, try changing back to the Windows stock curser and see if makes any difference.
