Check The Display Driver
Sometimes a mouse will work erratically because display driver is not working properly. The first thing you can do is disable graphics drivers hardware acceleration. Select Start | Settings | Control Panel, and open Display utility. In Display Properties dialog box, select Settings tab and click on Advanced... button.
In dialog box which appears, select Performance tab and move hardware acceleration slider control to None. If this doesn't solve problem you might try updating display driver. After locating a proper driver, this is done in same dialog box on Adapter tab by clicking Change button to open Update Device Driver Wizard.
Try a New Mouse
Most problems with mouse are caused by dirt or miscalibration. If cleaning mouse doesn't solve problem, procedures described above may guide you to source of problem. However, a computer mouse is a cheaply manufactured mechanical device. As such they don't last long. If nothing else works, maybe its time to retire that old mouse. ---------------------------------------------------------- Resource Box: Copyright(C)2002 Bucaro TecHelp.
