Try using removeChild with the pane's parent.

Thanks to Lyle's pointer - .create method has solved the pane creation problem. But there are other problem - how do I get rid of the pane.
Multiple calls to this class keeps stacking the pane over the old one.
In C++, I would have destroyed the old object - what do I do in FXRuby?
vPane.hide - looks to be a work around; but I think this will keep the old objects in memory. Please suggest a good way to close the screen.
