You want to call "update" to request an update to the display. If
you want an immediate update at that specific moment, call
"update(true, true)". For efficiency sake it is better to call
"update" and wait for the internal timer to fire off (every 0.333
seconds). So you have to decide what behavior is appropriate for
your situation.

I should probably override the refresh method so that it
translates correctly into the update mechanism.
Ok, but I'm actually calling Self.refresh (as opposed to me.refresh). My intention is to update the entire window. In the TextChanged event, I update all of the controls on the window to depict the state of the currently selected text. On Windows XP and Vista, I get a lot of flicker when I do this, so I lock the window with Aaron Ballman's window.FreezeUpdate function, do the changes, then call window.UnfreezeUpdate. After I unfreeze things, I need to call a refresh to repaint everything. This is where the odd flicker happens with FTC. Of course, on a Mac, all of this is not needed, but it still flickers as described if the refresh call is included.
