Adding disabled attributes to <BUTTON> elements in Safari does not have the desired effect.

Disabled buttons with text content are not greyed out and still respond visually to clicks (albeit without generating any onclick events).

In <BUTTON> elements with image content, the addition of a disabled atribute has no effect whatsoever.

In Mozilla Firefox 1.5 when you scroll the form so that it is off-screen at the top then scroll back on-screen the underscores on the first letter of each line sometimes do not re-appear again. When scrolling to the end of the form and backup again, and when the browser window is resized to a smal size it seems even more persistent. This bug is triggered by styling label:first-letter {text-decoration: underline}.

(ppknote: This bug is quite flighty, I myself saw it only the third time I tried the test page.)

An absolute positioned element inside a fixed positioned element disappears after scrolling down one page height.

div#sidebar { position: fixed; top: 0; bottom: 0; }

div#disappearing { position: absolute; bottom: 0; }

ppknote: Opera 9 beta has a different bug, but this situation is still buggy. It doesn't recalculate the height of the fixed layer when the page is resized.

When Explorer encounters a tag with the style white-space:pre inside a table, it will only print the first line even though it renders properly in the browser.

(ppknote: IE 7 beta 2 only shows an 'O' in the print preview)

IE crashes after updating several h1's css classes and div's display style with javascript. The bug only happens when specific styles are being used, in a specific order of updating the elements, and with specific laps of time between the updates.

(ppknote: complicated bug. Please read the page carefully)
