i have a wireless mouse ive used for a year or so with windows with no problems. i have windows on a partition on my MBP and the mouse works well on that also. when i have OSX open though , the mouse works, but is very jumpy, slow, and unresponsive. i have to give an extra firm push on the mouse buttons to get them to work when in OSX. i have played with mouse settings to no avail. is there anything i can do to remedy this, without buying a new mouse?
