I'm seeing the double mouse problem that some others have reported in the past, while running OPENSTEP 4.2. I am using build 3188 of Parallels, but saw it in the previous build as well. It usually shows up after I have been using the VM for a while, but once it shows up it continues, even across VM launches, until I reboot the physical hardware (MacBook Pro). I saw a hint that Windows users could fix this problem by turning down mouse acceleration, but there is no such setting exposed in OPENSTEP. Any recommendations?
