For a great number of beta testers though, Kestrel is pretty rock solid (as it is for me, I use it full time). And as urlwolf will attest, a well placed bug report will do more to improve the software than moaning that alpha/beta software is buggy.

for me, its so buggy I went back to 9.24, not to say firefox
bugs appear when you open more than 40 tabs (which is common when you do research on the web), keyboard shortcuts don't work, opening of autocomplete takes ages, cursor doesn't become hand-shaped over links, etc

And as urlwolf will attest, a well placed bug report will do more to improve the software than moaning that alpha/beta software is buggy.

no moaning here, you misunderstood, just posting my experience
and I did and do alot more to improve the software, me have posted numerous bugs and suggestions
but I disagree alot with opera devs' tactic and orientation

I may some day post some videos to demonstrate the bugginess of the current betas
