I cannot edit a field although the locktext is set to false

[Reinhold Venzl-Schubert]

Hi!

On my card there are 10 textfields, one of them ist locked and stay locked.
The looktext-button in the basic properties is not highlighted.
I send the message "set the locktext of fld "FrageR1" to false" to the field.
It stay locked.

What can I do?
What can be the reason?

Thanks
Reinhold
