[solved] True Launch Bar not selectable

Hi, TLB does not appear in my taskbar anymore ...
If I right click on taskbar, and choose toolbars, I can see True Launch Bar in the list. If I select it, nothing happens - it is not selectable.

Any ideas?
Thanks

I just found your tip to start TLB from the taskbar > properties > toolbars menu, but still doesn't work. It looks ok, but TLB does not appear. next time I open properties, TLB is no longer checked.
