I have this theory. My theory, which is mine, goes like this....................
You can only collapse the bloody thing by clicking the nifty bar.
If you don't click it, nothing disappears.
If you're stuffing around and a bar appears, then you click the damned thing, then the left panel mit der schoutenboxen disappears, it should not be a massive stretch of the intellect to conclude that the two events may be related.
This is my theory.
Devious, treacherous, murderous, neanderthal, sub-human of the West.
