The question is when will 10.52 or whatever version that fixes all its teething problems be released?Fixed post; 10.51 is a security release with few improvements in other departments.
The 10.50 line replaced the underlying QT-Framework with APIs directly supported on each OS. There are atleast 3 different backends that need to be brought into shape... and after Windows the Opera Team works hard to get the Unix and Mac Versions done.
I guess the necessary polishing of UI and features will have to wait until after that. Worst thing IMHO is that 10.50 does well in all those damn JS-Benchmarks which seem to became the singular measure of speed in the last few months, while often choking on rendering pages (which older versions dint)
