-// - why are we not getting keyboard input (focus?) on a mouse click?
-// - are we getting keyboard input (focus?) on tab?
-// - random freezes on Windows 7 when resizing headers or clicking new rows; likely another package ui infrastructure issue though...
-// - investigate japanese display in the table headers on wine (it has worked in the past in ANSI mode via Shift-JIS with what I assume is the same font, so huh?)
