However, I have a problem because I can't compile the HMI as is: compilation error. Do you think the project is unusable as is ? *Internal ERROR (detail: Couldn't access the property: ES2RTTypeModuleName - object type: VIEW_OCX).,,,2:22:46 PM* Thank you for your advice.

Can you compile other projects or a new one? If you cannot find the Screen where you used it, you can try to delete half of the Screens and do a compile, if this specific error is gone then its in the half-> then go halw ways down... should not take longer that a few minutes (better than searching every screen manually) Bye Murof
