Hi,
My initial tests with KDE-4.4.92 (4.5-RC2) is that it is working very well, a perfect and smooth update. There are some issues from the previous release I need to check and will do so later today.
I also decided to give qt-4.7.0-0.26.beta2.fc13 a test and some of the bugs I experienced with the earlier QT beta's have been fixed :)
Thanks again to all involved..
Colin
