(Don't think my 1st post on this took, so'll try again...)
I'm working on an app that will sometimes have two different
windows contain the same text. I want both windows to be editable,
with changes in one reflected instantaneously in the other, sort
of like the split-screen effect in MS-Word or Nisus.

Using standard TE calls, what's a good way to do this? Should I
declare a seperate TEHandle for each window and keep the text
within in synch by sending TEKey's to both? Or should I just
have 1 TEHandle?

Have tried the 2 TEHandle method and I get a glitchy problem when
I TEKey a cursor key to the inactive window, a caret (insertion
point) is drawn and remains. I can't filter out the cursor keys
cuz then the inactive TEHandle will lose track of where the
insertion point is s'posed to be. Maybe I should dicker with the
caretState or caretTime fields, but they're undocumented so I
don't know what to do... If it weren't for this caret problem, I'd
use this method as it otherwise looks good.

The 1 TEHandle method would seem to have a problem, too, in that
I'd have to do a EraseRect; TEUpdate combo to keep the inactive
window properly updated, and the ensuing flashing would look bogus.

Any Hints? Thanks! - Ross
