Merged. I also took care of that uninitialized viewbox. The following example works now:

| p |
p := MorphicProject new.
p world extent: 800 at 600.
10 timesRepeat: [(ToolSet explore: Morph new) openInWorld: p world].
(ProjectViewMorph openOn: p).

An extra layout-udpate might help to also show the docking bar. Let me try that out.

Best,
Marcel

Hi all,

currently, if you create a ProjectViewMorph on a new project (for example, via TheMainDockingBar), the thumbnail is missing unless you enter the project. The project type does not matter.

The attached change set should fix this issue. Would you agree to merge it into Trunk?

Thanks to Marcel for the help!

Best,
Christoph
