On win32, changing the title of a modal dialog doesn't appear to work.

The included program demonstrates this problem.
Bring up the program
Click on "Show Modal Dialog"
(note the dialog title: "New Title: 1")
Click on "Close Modal Dialog"

Click on "Show Modal Dialog" again
(note the dialog title is STILL "New Title: 1", should be "New Title: 2")

The problem only occurs with modal dialogs (setTitle on non-modal Dialogs
and Frames works fine), and it only occurs on win32.

Also, strangely enough, if you call setTitle *while* the modal dialog
is showing, it works!

Unfortunately, though, this bug affects Swing because for our Option dialogs,
we re-use dialog instances (to get around a bug in Solaris where disposing
dialogs causes a SEGV), and this bug causes titles to be incorrect.
