There's a bug (one of many) in TRichEdit. If you send text directly to
a rich edit (using paste or .lines.add()) then it hits a size limit. If you
load
a file into the rich edit, then this lower size limit is eliminated (does
not exist).

In the past I have first loaded a small file (say, windows.ini) into the
rich edit,
cleared this text immediately and then used .lines.add() to produce
memos with very large text sizes.

hth.,
William.
