As my system was bogged down with spyware, viruses and all the scans and fixed could not help, I decided to reinstall the OS (XP Pro). All went well. I lost a few document files but was able to recover them with the help of Tek-Tips. My problem is that my mouse function is slow and sluggish. I have a scroll wheel on my mouse. It takes forever to scroll to the top of a page. Same with using the down arrow. Programs open and close fine, its just the problem with the mouse and down arrow being sluggish when scrolling. It is definately a delayed, slow and annoying process. Any ideas?
