MalamiR you are a genious ! Your solution fixed my lost button in hebrew vkb. You have a typo there coonf instead of conf.

Here the start of my desktop.conf now:
[Tasknavigator]
X-Type=panel_box
X-Position-X=0
X-Position-Y=0
X-Size-Width=480
X-Size-Height=0
X-Orientation=left
X-UI-Policy=libtasknavigatorpolicy.so
X-Is-Ordered=1
X-Config-File=tasknavigator.conf
X-Plugin-Dir=/usr/share/applications/hildon-navigator

Please someone post the one in the Diablo5 package so we can see what is causing this bug.
