Techrepublic/Mozilla email links

Interesting problem with the Techrebublic newsletters, as well (rarely) other emails with links. If I click on a hyperlink, with Mozilla as my default browser I don’t get taken to the link, instead I end up with a blank page with a browser tab of “clicks (GIF Image, 1×1 pixels).”

However, if I paste that URL into IE, no problem; I go right to the page.

This seemed to crop up out of nowhere some time ago; I can remember everything working fine, then *poof*

With the exception of Techrepublic, about 99% of my email links work fine. For the record and just in case it’s a factor, I’m using Eudora 6.2 and Mozilla 1.7b.

Thanks in advance.
