There was a later (hotfix) version of VMM.VXD issued to fix a problem when used with certain specific hardware,
(although the underlaying fault was probably in the vxd file).
(I mention because there is no mention in the SP changelog of VMM.VXD, or the MS 'Q' or 'KB' number 254087).
Thanks, I didn't know I hadn't added it to the changelog. I will add it the changelog and the file will only install if you have a laptop. Thanks guys.
