Yahoo Mail "Beta" sucks

I work on two machines in the mid-to-high 2 Ghz range with 1 gig of RAM on a regular basis. And yet the new YAHOO MAIL "Beta" has consistently crashed and throttled Firefox multiple times within the last few days. If your AJAX app does this you're worse than Microsoft.Client: Is my app Web 2.0 ready???Me: Oh yeah baby, you won't be able to find a desktop it won't crash!
