when I click a link it jumps to top of page

Sometimes when I click on links (or buttons I believe) in Firefox, the browser jumps to the top of the page rather than following the link/button. Any ideas how to fix this?

 

I will keep an eye on this thread to see if anyone can come up with an answer. Sometimes, when I click on a link such as a link in this BBS, the browser does not go to the link location. The page simply jumps up about an inch and does nothing. Clicking on the link again acts normally.

This has been going on for many versions of Firefox and through a reformat and reinstall of Windows. It happens maybe once a week and I have decided that it is just one of those things that I have to put up with.

I'm lurking on this one....
