I'm not sure the background has any effect, but you could easily test that-- change it to black for a few days and see what happens. What I suspect is the case, is that the software (or firmware) that runs the mouse has a much higher duty-cycle at your machine, whether it's the BIOS, the video card, or Linux, I couldn't venture an opinion. If you could temporarily set up Linux on your brother's laptop (the same version you use) and then test, you could determine. if it's hardware or Linux. If it turns out to be hardware, you should alert the manufacturers of your machine and its video card. (And the mouse!) They will certainly want to know, since most of their customers are using Windows, where the problem will also exist. If it turns out the other way--Linux--you should file a bug report. --doug -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
