Hello,
I know, but the problem seems to be located in the Windows Memo, after a
few tests it behaves different if WM_SETREDRAW is involved and the back
and forth for the text happends because to add text the code must select
a line (or a new empty line to add new text) and replace it. This
replace effect removes the line, adjusts the memo and then replace its
position with the new line and add a carriage return and adjust again
the memo. So lines goes up and down for each new line added.
From my point of view this is a Windows memo bug.
Using Memo.Lines should work better, if possible at all. It should split
the text into lines, update the lines, then pass the new text back to
the memo.
