Theres a super cool add-on for firefox called Download Statusbar, and instead of the extra box you just get a little loading bar thingy in the status bar for each download. If you close FireFox then it can either carry on next time you open, or it can be set to carry on with your downloads in the original sownload box. I've got FF3, IE6, Chrome, Opera and Safari on this computer for website testing, work have got IE7, so I can check for differences between IE6 and IE7, it's surprising how many there are! I've hardly used Chrome, I didn't like it when I did try it, I'm used to FireFox with all my Add-Ons. Is IE the problem by any chance? I sorted mine by adding in a section of code at the bottom that only IE reads.
