Accessing SL Beta through SL viewer?

[Kittenix]

I want to log into SL BEta but it seems the only viewer that allows that is Firestorm? Which runs too slowly and keeps crashing on my computer.

Can I not access SL Beta through the official SL viewer? I've looked at the start-up page but can't see any way to head there - it only lets me log into SL.

 

Any advice much appreciated...

Theres a setting in preference that will let you access the Beta grid too. (allow multiple grids? )
