I am refactoring the mergable grid widget, used by the captioned, to an event-based design and have pushed changes to the master branch in github. I pushed the changes as Jervis Liu is completing a major re-organisation of the Guvnor code-base this week and I didn't want to end up with merge conflict hell :) The changes, at this stage, are incomplete. Consequently the captioned editors do not fully work at the moment in the master branch. 5.3.0.Final is unaffected. So, if you get the latest code github's master branch be warned. My changes will complete this week or early next. With kind regards, Mike
