A customer just pointed out to me that as of FlexSim 2023 it seems like template popups (the one used when no other popup is specified) have turned readonly.
I assume (and hope, because it would be a painful exercise to create all custom popups for this customer's module) that this is a bug.
Steps to reproduce:
In any code editor, use the /**/ notation to create a templated script, e.g.
- return /**The value is: *//***tag:value*//**/42/**/;
Click the 
Properties button.
Expected result:
The template popup is editable:
Observed result:
The popup is readonly and greyed out
