By the way guys, thanx a lot for all the work you've done: )
This is not a bug at all. This is a feature request. I think i'd would be nice to have the same option we have in xfce4-systemload-plugin, i mean, we can check/uncheck the text written beside the colored bar.
oops, i forgot:
I'm running an uptodate debian wheezy.
