Glad to see it go.
This was the most painful thing to get rid of because you couldn't ever isolate it. I spent entire days removing chunks of code from a page, until finally arriving at this:
<html><body></body></html>
Refreshing the page in the browser still gave that Operation Aborted error about half the time. It's like it was cacheing the ghost of the original page and executing its scripts.
Now to wait patiently until IE7 goes away so that I don't ever need to dive into that again.
