Hello,

I am having great diffuclty getting an embedded  JScrollPane in
aJFrame to validate as the user resized this JFrame. I have tried
everything. It appears that the JFrame's ComponentAdapter does not fire
also (i was hoping to valiadte with this as frame resized).

Can someone offer a suggestion? I am hopelessly deadlocked.

many many thanks,

mike
