Excellent questions, Iurox.
1. Does this happen in other programs or just in Outlook?
**Different programs (Mostly Explorer & Word)
2.Have you been downloading Windows updates regular?
**Been neglecting/ignoring mostly (upgrading every 2- 3 mos.) until a day or so ago.
3. If it is just Outlook make sure your updates are up to date!I have had weird things with outlook in the past and updates always seem to fix it.
**I heard the same thing.
4.If this happens in other programs,your mouse may be junk, or dirty. I know this sounds silly but it is very possible.
**Nine said similar. Should I replace it with any of the other trackballs (mostly older Dells) in storage just to see if it makes a difference?
5.What type of mouse do you have? Laser or the old trackball. Is it new?
**Dell Trackball- approx. 1 yr.
6.Are you running XP or Vista?
**XP
7.What version of Outlook?
