This problem seams more general... adding an application to the
"favorite" when connected to a docks station produce the same freeze
when laptop is standalone. The workaround is to to do this BEFORE
connecting to the doc station the first time. :-(

I found also some problems with kwallet when seting up a wifi
connection: it was requesting for a password but kwallet/centos was
unable to focus in the popup windows to allow entering the
password...:-\ (standalone laptop at this time)

kde seams to have some trouble in dynamic screen configurations. I
switched to Xfce which just runs fine and do the job!
