But surely it doesn't need to redraw the table as the mouse moves unless
the model tells it that data has changed? I am only sending
ModelChangedEvents when they are required, and I was logging these too
so they're not being sent too frequently. Moving a mouse shouldn't cause
redraw events, the OS handles that so what is it redrawing? I need to
find a way to stop this! Any more ideas? Any authors of JTable hanging
around? :-)

No custom renderers (yet!) Lookup of data values is done in a 10000+
element hash table...
Getting annoying with Swing here...
