Hello all,

well after much searching and swearing I managed to find a case where I can
switch on or off the case of whether or not a JDialog gets cleaned up or
not....and the culprit is JdbTextField.
If I put a JdbTextField on my dialog, then the dialog will not be GC'ed.
Every time I display my dialog I clean it up afterwards (dispose() ). One
instance nevers gets cleaned up. If I put a normal JTextField on the dialog
instead, all instances get GC'ed. If I explicitly remove the JdbTextField
control from its container during dispose(), then all instances get GC'ed.

JFrame does not appear to be affected in the same way by the JdbTextField
control....I am still searching for the culprit there.

Can anyone from Borland perhaps explain why the last (or at least one)
instance of a JDialog does not get GC'ed if it contains a JdbTextField?

Thanks in advance,
David Sykes

well after much searching (and swearing) I managed to identify JdbTextField
as one culprit for the JFrame not being cleaned up. Actually in this case it
was a JDialog, I will check tomorrow to see if it is
