This isn't the correct group for questions about DHTML. This newsgroup 
is for discussion of the implementation of the JavaScript Language in 
Mozilla. I've set the followup to npm.dom.

First, 1ms is too short of a time interval. Mozilla and MSIE will both 
use a value closer to 15-16ms when shorter intervals are used.

I tried a testcase on a both fast (3Ghz) and slow (300Mhz) machines and 
found that Mozilla, Mozilla Firefox both trunk and 1.7 branches behaved 
similarly to IE.

Perhaps you could point to a public url or attach a testcase for us to 
look at.
