How lock text & data fileds to prevent "graphical" changes but allow editing and fill in?

Hi,

Does anyone knows if I can lock text and/or data fields to prevent any graphical changes like moving or stretching?

I tried it with the level lock and the element attribute lock, but it prevents also editing texte and fill in data fields.

I hope there is a possibility to do this. If not......., I would be happy if this could be added further :)

Thanks

Regards
