There's also an annoying "feature" in Chrome where it expands the height of the box in strange ways.
Actually i like that feature since many website use fixed micro-sized edit boxes that you can barely type a sentence in without scrolling 
If you could let us know what other browsers (and version) it is being buggy in, that would help.
Internet Explorer 8
SRWare Icon 9.0.600.2 (74100) http://www.srware.net/forum/viewtopic.php?f=18&t=2190 ( i'm using the portable version, I'd like to see that feature in IE9 )
Firefox latest official version 3.6.1.3
