In KDE taskbar, KRDC appears mixed with other apps after leaving fullscreen mode

Hi,

Dunno wether KRDC is to blame for this (it only happens with KRDC) but when leaving full screen mode from a RDC session, the KRDC app mixes over / with other apps in the KDE desktop taskbar. It's window appears superimposed with an another one in a transparent way, instead of showing in task bar as a separated app.

If starting a new app, or moving the app to my 2nd screen display then back to 1rst screen, the windows separates again and show well as expected in the task bar. But again, going to fullscreen mode then back to windowed mode, the KRDC app shows over an other.

I'm using Kubuntu 11.10 (but this happens from 11.04) with a dual screen display with nouveau driver.

Again this only happens with the KRDC app.

PS : Tell me if you need any more info or log file or anything to troubleshoot this strange beahviour ?
