Easy to check: try another mouse. No need to install drivers, just plug it in. This points to hardware problems, or excludes them.
If no luck, boot into Safe Mode, and see if it works then. If it's some malware, good chance this helps you to detect so.
If no luck, uninstall the software that came with the mouse, and use basic Windows 98 support for it. A simple reinstall might be a solution.
And use housecall.antivirus.com to find any interfering malware.
Hope one of this four points helps.
My mouse pointer has recently begun to fly to the side or top and freezes. I have to re-boot to normalise it.
Has anybody any experience of this. I suspect the fault might be a mouse suffering from anno domini! There are various protection programmes which were installed prior to the fault. I have not installed any new programmes recently. Thanks in advance !
