I seem to be having a problem with TEUpdate.  When I call TEUpdate
with all of the required parameters, nothing happens.  According to
Macintosh Revealed (okay, not the authoritative source but that's what
I've got), a TEUpdate should automatically do a TECalText and then
update my text fields.  Well after doing this nothing happens.

Something else wierd.  I set the teLength field of my edit record to
the length of the text in the hText field, but both TECalText and
TEUpdate set thee teLength field back to the size of the data area
pointed to by the Handle which contains the text hText is pointing to!
Because of this all of my scrolling calculations are off because every
update resets the text length field!  Can't calculate how much to
scroll when this happens!

Actually there is ONE way to get TEUpdate to work.  I call TECaltext
explicitly before doing the update, but this has the same problem with
reseting the length field.  TECalText munges it as badly as TEUpdate.

Anyone with wizard experience and the TE package?  This one is really
difficult to handle. :-)  Get it?  "Handle."  Kyuk kyuk.
