Description Craig 2006-06-02 13:04:00 PDT 
Once this page loads, rolling over any images or links causes the images or links to disappear.  Once you click on a blank area, the content comes back.

The problem doesn't occur when JavaScript is disabled.

A search through the nightly builds points at the fix for bug 6268 as the likely cause for the regression.

The offending page manages to confuse the pending stylesheet count by dynamically inserting LINK elements. With the count remaining indefinitely >0, the "not available yet" style is returned as the hover style for all elements, making them disappear on hover.

This sounds very similar to a Colloquy hover bug that I have never been able to reproduce. Colloquy does dynamically adjust the link elements to load new stylesheets. When you hover over nicknames or other links they disappear, but it would happen after hours or minutes of everything being normal. (Or maybe they just never hovered over a link until the point it gets noticed?) A few users have reported it along with Darin and John Sullivan, but very uncommon.
