Error "Attempt to read or write protected memory" in MAS

Question

Hello,
I am always getting the error message "Attempt to read or write protected memory. This is often a indicator that other memory is currupt" as soon as I try to add a new Method to a BO. What I do is
1) Open BO in Code Mode
2) Open Tab "Document Outline" ; right click on Method and "New.."
3) I enter the Method name i desire "Z_CPB_RetrieveStockInfo"
4) I enter the specific signature i need "Public Function Z_CPB_RetrieveStockInfo( ByRef Sfmara As String) As Object"
5) I press ok and get the error message in the first popup.
6) I get another error Popup "Cannot open the code window. Reason: The object may have been deleted from the Changelist"
The method "Z_CPB_RetrieveStockInfo" listed in the "Document Outline" Tab below Methods, but not in the selection box above the code. If I restart MAS I can see the method in the code and in every selection box. It is also possible to enter the code into the method, but as soon as I saved and restarted the machine, the code is gone and the method body is empty again.
Does anyone know what's going wrong?
Regards,
Andreas
