hello,

I have a JFrame that I put two components, one on BorderLayout.CENTER
and the other is at EAST.
When I cover with another window, and then uncover,
the part that is uncovered does NOT refresh.
It is unbelievable.

I put the component at EAST to another JFrame and no such problem
happens. The component on CENTER uses some library and rendering
that I didn't write myself (JUNG's GraphDraw).

What could be the problem?
Or, how can I fix it?

thanks,
alex
