May I ask if you are using any mouse pointer enhancements not provided by Windows itself? That could make a difference.
Also, if using one of the regular pointer sets and sizes (and please note the size) from Microsoft, which one? You should find this information under Control Panel, Mouse Properties, Pointers tab.
