Here is an online article which seems like it would cause more trouble than it might help in any understanding:
specifically the section that goes like this:
--------Mouse software or driver conflict
- Open Windows Device Manager.
- Expand the mouse (mice) option in Device Manager by clicking the + symbol.
- Remove all mice listed by highlighting each device and then pressing the Delete key on the keyboard.
If the mouse still does not work in Normal Windows, follow the basic troubleshooting steps for your version of Windows.
That step #3 seems like a big risk. If I do that step, then will the mouse either work WORSE, or completely stop working?
The problem I hope to check is that on a particular computer here, toshiba laptop, Windows Vista, a computer restart or fresh start with ANY mouse plugged in, the mouse, ANY mouse, will NOT work; UNTIL the mouse is disconnected and then reconnected. Forgot to say, USB-connectable mouse.
There is found already a similar topic about the problem on the toshiba laptop forum and there were no responses.
