ProTools10HD keeps scrolling the edit window

[djani]

Hi, haven't seen that anyone have this issue.
I recently started using a gaming mouse R.A.T.5 as it have convenient left/right scroll and zoom in/out buttons.
But sometimes when I edit and zoom in or scroll within edit window the ProTools continues to scroll to the right of the screen till the end of a session. And nothing I can do to stop it or get back edit window to the beginning of the session. I have to restart Mac and then its all back to normal.
During this event I can normally playback the session from the start but the issue is only visual. I'm on mac OS X 10.6.8. MacPro 8 core 2.66 GHz Xeon.

Wonder if anyone knows the trick I can do to stop it from continuing scrolling without restarting computer. (I tried unplugging/plugging mouse, not workin').
