I have a tool that I created from a Python script which I update from time to time. Usually I will right-click the tool and choose Import Script, but lately this has been unavailable, as shown below:
This has been happening to almost all the tools I create, usually after a few imports. The problem is that if the script is cached the only workaround is to create a whole new interface, which can be pretty time-consuming. Does anyone know why this happens?
I found this post on the Esri forums describing the same problem: http://forums.arcgis.com/threads/70829-Python-Import-Script-grayed-out
