Hi John,
Thanks for your answer.
I have tried:
- take newly created process without parameter
- add new parameter, save, open debug\startup parameter window > error message
- close and reopen process
- remove parameter, save, close, reopen process, open debug\startup parameter window > error message
Tried various combinations with adding, removing, saving, closing & reopening the process, always with the same error message.
Meanwhile I have created a support ticket and already got reply saying this is a known issue and will be fixed in 6.5
