Problem when loading large text into DBMemo box.

Windows 7, SQLite3 database.

I loaded a whole book, in text format (1,882 KB) into a Memo column in
my database/application.

It took it fine, and can read it.

But I have a  WordWrap select button that works fine for memos with
few lines.

For this large text, when changing from default no-wordwrap, to
wordwrap, raises a problem.

The work-around is to FIRST set to WordWrap, then enter the cell with
the book loaded in the memo cell. Then it works just fine.

I don't find any other alternatives, and it may be something that
needs to be addressed by the Lazarus team.

Thanks.

PS: The same problem happens if after the long memo is loaded (as
described above), I then click to disable word wrap , back to default
'no' wordwrap.

The error message is: Failed to create win32 control, error:0: The 
operation completed succesfully.

Press OK to ignore and risk data corruption.
Press cancel to kill the program.

Furthermore, I trapped the problem with Try/Except, which allows app
to continue.

However, DBMemo then is no longer available (disappears), and hence
app is not functioning fully.

So it has to be restarted. Database, though, continues to be OK.
