Well I don't wan..... yes, Steve
You did not change any of the values you mentioned above, right? These values were not present, and after you updated the mdl they were present - is that correct?
--> hu, that goes into design.
1. You can change both the model size and ui values at the same time
2. You can delete an ui value by setting its content to empty
3. You can change an ui value
All above is true. I need to think about how to translate that into code logic (VB6 controls have no dirty flag).
