Browser is frozen during high-load phases. Reproducible: Always Steps to Reproduce: 1. Load the given URL 2. watch task monitor Actual Results: High CPU load. Expected Results: Low CPU load. Not sure if this is an actual browser bug or just stupid Javascript code. But IE does not show a similar behaviour. So I guess it's the Javascript engine that performs bad.

Reassigning to Browser-General until we can get further information. I'm not seeing this at all; the site loads fast, with normal CPU load. I'm using Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.4b) Gecko/20030515 Machine: WinNT4.0(SP6), 128M RAM, 500 MHz CPU

I can confirm that scrolling on this site will consume nearly 100% of the CPU on the 20031006 nightly, Win 2000. This has to be a dupe of one of the other slow-scrolling bugs, but I can't quite figure out which. It has a tiny background image and uses no fixed-position elements. Perhaps bug 187822? I'm sending this to ImageLib since that bug looks like the best culprit to me, although I suppose it could be a layout issue. I apologize if this is the wrong place.
