Choosing under Preferences->Mouse:Cursors you can choose to make your mouse cursor Small , Medium, or Large. Well it seems this only affects the first person who logs in. Once that person logs out, the next person to login or the same person who just logged in will nolonger have a large (or Medium) mouse cursor, it will stay the same small size untill you move the mouse over a application window (ex. firefox), but once you have the mouse back on the desktop it becomes very small. If you use high resolution monitors or have disabilities this can be a real pain.
