Error when camouflaging UserForm elements

This problem results from an internal Excel error that is inadequately documented by Microsoft.

Under unfavorable circumstances, it denies access to modules for no apparent reason.

There are two ways known to resolve the error:

– Restarting of Excel

– Repair of the VBA project:
  Exporting the affected modules,
  delete and then re–importing them.


This option allows a repair trial.

In this case are ALL VBA modules are exported, deleted and then re–imported.
