Thanks for your time!
As you said, in another part of the code I redraw the field.
I changed it as you said (StrCopy(newText, rP->login)) and I obtained an
error at running time.
(It was with an equal symbol, because at the beginning I catch the whole
record -the structure- (newText was ConfigurationRecDBType type) and then
that was correct, I changed it trying to get just one of the fields of the
structure and I forgot to change that. Thanks for that tip but seems that
there is something else.
