Follow-up: to make popup menus work, you have to make sure you display
them from the AWT event thread. Since you're probably responding to
MouseEvents from a behavior, wrap your code in this:
EventQeue.invokeLater(new Runnable( {
run() {
popup.show(component,x,y);
}});
And all is good onc
It works! A simple workaround until the bug is fixed. Thank you!

I would like to give my canvas the 'focus' so that the

No, as far as I know there is no way to do this. Windows (for example) just
doesn't make it easy for you. Read:

For an example.
Most of there techniques consist of drawing into a partial image and then
blitting the image. T
