I have two daily builds, running Kubuntu 12.10 in VMWare Player Virtual Machines. I keep the daily builds up-to-date with a: sudo apt-get update sudo apt-get dist-upgrade On both, I have added the Speller widget to Task Manager Panel, which I have set to Auto-hide. On Kubuntu 12.04, when I click on the Speller widget, its window pops to the foreground, covering the lower right corner of (say) rekonq. On Kubuntu 12.10, it seems to stay in the background behind (say) rekonq, which I have to minimize to see the speller box.
The speller widget seems to come to the foreground now. Still on Daily Builds of Kubuntu 12.10 in VMWare Player Virtual Machines. KDE - Be Free! Platform Version 4.9.1
