As a jar file my application moves focus via tab and CTRL tab keys on all systems. It moves the focus as intended as an
applet on MacOS. (Strange: moving from the default button takes two tabs.)
When used as an applet, the results are incorrect on Windows on Linux. They differ between Windows on Linux.
On Linux the focus traverses normally until it reaches the starting point, the default button, then apparently moves to the browser or a higher window.
On Windows, the focus doesn't exist anywhere until a component is clicked, focus then moves normally.
I'm doing a requestFocusInWindow for the JPanel holding the components. And the focus moves correctly when the app is run as a jar file on all systems.
Thanks,
Chris
