My wife was tring to do uor taxes on turbo tax. It keeps coming up with the error message "XMLHTTPRequest not supported" Anybody have any ideas on what it is, or how to fix it? I have also noticed lately that sometimes, if I click on a link, or book mark, the browser will close itself. Not sure if these two items are related or not. We are running a Dell optiplex with Windows 2000 professional and useing the opera browser.
