I am using WinXP Home SP3, and have a HP Wireless Mouse (used it for more than a week without problems).

Yesterday I have found that the mouse buttons configurations (left/right) are interchanged. I went to Control Panel>Mouse Properties>Button Configuration, and switched it to the one I desired (using the left button to be the primary button). Clicked 'Apply', and then 'OK'.

The configuration is succesfully switched... BUT JUST AS LONG AS THE COMPUTER IS NOT RESTARTED.

Whenever I restarted my computer, the Right Button becomes the primary one again.

Please help me to make this configuration permanent (until I switch it via Control Panel again).

Appreciate the help from all you good folks in here.
