Browser Compatibility

I was wondering if there was any info available on which browsers Zoho Sheet is supported under.

I realize that this is still in beta, and documentation is yet to come, so the question is no doubt a bit premature :)

I've been using Camino 1.0.1 (OS X), and have experienced a small bit of UI weirdness. The trash icons for deleting sheets, for instance, are not clickable, and occassionally the formatting buttons don't work.

In Safari 2.0.4, everything seems to work as I expect, but the style sheet isn't quite right, and so some visual elements overlap or collapse in awkward ways. The input button graphics also don't display.

I was thinking of downloading FireFox and seeing if it handled any better, but if there is another browser on OS X that would work better for Zoho Sheet, then I'd be interested in knowing that ;)
