This happens after the first use of a context menue. At that time the first context menue pops up in a semi-translucent mode. Normally the context menue in a chart appears instantly in a fully intransparent mode - only the first time that context menue is invoked when I get a context menue that seems to "fade in", and then the bar remaines like a detached top level window.
The bar disappears after some time - the time varies. Once its gone any reattempt will recreate the issue.
I presently can not reproduce this on purpose. Possibly it relates to an issue in the windows forms namespace just on my machine (2.0SP1)
Thanks ahead
