View is failed in model builder

[NorbertPaul1]

Hi,

the views (not the function) of my models are regularly failded when i want to edit them:

Then i open Programm Properties and change the style an press ok. Then the same a secound time, to change to style 1 back. Sometime this works to recover the view. Sometimes, it helps, to run the model.
