After some digging around i figured what to do to draw text in the
status area, so i wrote a simple clock using threads. I can't
understand though why the clock doesn't get updated sometimes even
though i call drawbar() directly from the thread run method...
Any help would be appreciated, and also how could i do the same
without using threads?
