I am using Windows 2003 and have visited the web-site and downloaded the defender program. It has not stopped my computer from closing all the tabs and windows when I left click on a link, file, attachment, or anything that requires a left click. I am still receiving the debug or send error report prompt and at times the Dr. Watson postmortem debugger prompts. This happens 75 to 90% of the time. What can I do to fix this?
