Hi Malcolm,

I made a few testprograms that work fine with your code. Now I made a 
full keyboard (Belgian AZERTY) and I'm having a problem I can't solve.

The keyboard has some "special" characters : é§èçà and others. Those are 
not 1 byte characters. When I add them, they appear in the memo, but the 
next character seems to erase the memo. If I have already some lines in 
it, all disappears and the cursor is on the first line, fully left.
I add the characters with a string :

Kars:='§';
Memo1.Text := Copy(Memo1.Text, 1, testcaretpos) + Kars + 
Copy(Memo1.Text, testcaretpos+1, MaxInt);

Actually, I do this in a procedure with Kars as a parameter.

Any suggestions where to look ?

BTW, I tried this on Lazarus 1.0 on Linux.

Thanks,
