[Chris Pavlina <pavlina.chris@xxxxxxxxx>]

I'll try this later today, but I'm suspicious it'll work. I don't have 
trouble capturing any other special keys (tab itself even works on both 
Linux and OS X), and it's not just ignoring tab, the whole application 
is *freezing* when I press tab. I can't even drag the windows around, 
it's completely solid. Also I should add that it happens even if I never 
bind the EVT_CHAR handler - the dialog just does not like to receive Tab 
when there's nothing in its tab order, for some reason.

The easiest solution may be to create an invisible component that exists 
in the tab order...
