I just did the latest update on KDE4. It’s 4.1.2 release 44.2 & I’m happy to report, you can change Desktops now!
So step on over to a yast near you & get the latest KDE4 for yourself!
Now my disclaimer: The only thing I checked was the Desktop settings,I don’t know if something else is now broken.
Yeey! It work’s again, but for me this release is significantly slower that the other versions before this can’t-change-desktop problem.
