Hi,

When I execute JFileChooser.showOpenDialog(this) and then choose the
ESCAPE button to terminate it, the application window (this) is left
with messy remnants of the showOpenDialog visible on it.
I've tried many ways to clean it up.  No success!

Am I doing something wrong?
All help will be appreciated.

My code is below

  boolean openjMenuItem_actionPerformed(ActionEvent e) {

interactionsController not created yet.

     //  or interactionsController still not created i.e. interactions =
null.
