Eliot Miranda uploaded a new version of Tools to project The Trunk:

==================== Summary ====================

Name: Tools-ct.1021
Author: ct
Time: 3 January 2021, 8:44:07.705149 pm
UUID: de36bf14-60b2-d745-9ade-df88c56b645c
Ancestors: Tools-mt.1019

Hotfix for fatal error in MVC projects when switching from an explorer to an inspector.

Regression since Tools-mt.998 (elimination of 'Active' variables): [Project current world] now consistently answers a ControlManager instance in an MVC project rather than nil. Unfortunately, ControlManager does not implement the stepping protocol like Morphic does ...

For now, let ObjectExplorer >> #world only answer actually steppable, i.e. morphic worlds, so stepping is disabled safely in MVC. Note that, however, at a later point we might want to talk about stepping support for MVC again ... maybe? The Process Browser already supports it. :-)
