Hope you can help because I am at a loss on thios one.
As part of the actionPerformed(ActionEvent) method on a window (call it A), I open-up a second window B.
The problem is that window B is only partially displayed and window A goes blank whenever I move window B around using the mouse.
All is fine if I open window B outside the event handler as a test so the problem is not with window B.
Seems to be that this weird display behaviour might be caused by the system being blocked because it is processing an event on window A. How can I tell the system that I have finished handling the event before I open window B?
Any ideas is much appreciated.
