One more thing to check, Crazy Ferret Lady

, is there a "Back" button within the dA site while you are viewing the image?
No, dA doesnt have a back button that would send you to the previous page.
The strange thing is though, is that sometimes (though rarely) if I double load the page by clicking on the dA logo or someone's gallery button, when I click back it
will go back or more often it will attempt to go back to the previous page, but instead it reloads the image and when I click the little down arrow, it shows "HTTP 400 [something]", and then several links to what I assume are ads.
As far as disabling my add ons, I'll give it a shot, but like 90% of my add-ons ARE disabled... I did that because I'm having issues with tabs too. I'll close a tab and a little box will pop up telling me that IE has stopped working and that its looking for a solution.
The last time it did that, I had too many add-ons going on and it was bogging down my browser, but disabling them hasnt really helped.
EDIT: Wanna know something sad? I opened IE 64-bit and its not doing it. >.< Same thing with no add ons, so now I have to go through and figure out which one it is... joy.
Okay, so I cant seem to find an add on that would be causing this. Running it in 64-bit and without add-ons "fixes" it, but I cant find anything. Only one I could think of was the Bing Bar, but disabling that changes nothing. And now when I hit "forward", instead of sending me to dA (or whatever dA page I was viewing before an image), it sends me straight to the image but it flashes on dA before it goes to the image.
EDIT: BTW roncerr... your suggestion fixed nothing. Reset IE, still doing it.
Now I'm stuck with a screwed up browser and Norton. Fixed them, but still having the problem.
