For years now I have been able to left click on a link in an email and go to a website. A couple of weeks ago this changed. In Thunderbird, clicking on a link does nothing. In the Outlook Mail client, clicking on any link brings up a program to setup the Ask Toolbar. Just to see what happens I have let the setup complete and opened IE Explorer. The next time I click on a link in Outlook, it wants to set up The Ask Toolbar again. If I click on a link in Google Talk to get to my Google mail, nothing happens.
Links in a browser still work. If I right click, on a link in Thunderbird, I can save the link target, paste it into a browser address bar and get to the site that way. In convenient but not disasterous. However, I am completely locked off from my googlemail.
Any ideas where the problem is and how to fix it?
I am running XP Professional on an Asus sPresso with a 3MHz Pentium IV and a gig of Ram and a 160 Gig hard disk.
