That's what I had guessed, but having it confirmed makes me feel better.

Moreover my ShowError is not protected from recursion, because 
Application.ProcessMessages is called before incrementing ErrGet. 
Therefore in case of recursion, it will attempt to process again the 
same message.

I would appear that also Application.ProcessMessages is not protected 
against recursion, which is possibly a bug.

Thanks a lot,
