Remember I was raving about the new Mozilla 1.2 version here? Well, it has only been just a few days and already there is a problem. A problem so bad that Mozilla themselves have pulled downloads of the software.
"The newest bug affects some Web pages developed with dynamic HTML (Hypertext Markup Language), or DHTML--an advanced programming language that combines JavaScript, cascading style sheets, and the Document Object Model (DOM), among other technologies, to create a page that can change dynamically after it has loaded onto a browser. "
HOWEVER as of yesterday, Mozilla have posted a new build here which apparently has fixed the problem.
If you installed version 1.2, then I recommend that you upgrade to version 1.2.1 as soon as possible to avoid any problems.
