[AccessD] Too much type ahead in RTF box

Hi all

A client has an A97 app where they can type in formatted comments in
an RTF box bound to a memo field. The box is the standard MS Rich Text
Box. OS is Win98.

It works fine except that some users claim that they occasionally
experience that they can type the first line beyond the right side of
the frame - the line is not broken until they do something else
(click another control, browse records, select menu etc.).

I cannot replicate the error here and have no idea what to look for or
where to look for a solution.
Has anyone seen something similar?
