most recent version of all major browsers.
Betas are kinda funny like that Rebel44. You might say they're summa time apps.
Summa times they work and ... summa times they don't. Have a nice day.
While I agree that it shouldnt be priority, it also IMO shouldnt be more or less ignored, just because its beta - its public beta and IIRC IE9 beta has 25 million users.
Like I said this is only forum that I know of which has such problems with it.
I can live without IE9 beta compatibility, but I would prefer if it worked.
