I'm not sure what options "Advanced System Optimizer" provides, but I do know that the free "Tweak UI" program in "Microsoft PowerToys for Windows XP" provides several mouse speed-control features. Scroll down to find "Tweak UI" on the right-hand side:http://www.microsoft.com/windowsxp/Downloa...ppowertoys.mspx
In the "Tweak UI" tree list, the Mouse
dialog allows you to control cascading menu speed and mouse sensitivity. The Mouse, Hover
dialog allows you to control how fast/soon a hover will be detected. The program itself provides a detailed description of each option in the right-hand pane.
