[josm-dev] modal dialog and message box block each other - solution?

[Sebastian Klein]

Hi,

To the Java experts here:

We have some situations where PleaseWaitRunnable shows a progress dialog 
and another confirmation message box is shown. Then there is a chance 
that both dialogs block each other.

What is the best way to avoid this? Can we use any modal-feature of Java 6?

(Note, this never happens for NMEAImporter where 
JOptionPane.showMessageDialog is used.)
