As you can tell I was testing the latest trunk image and discovered the
"automatic" bug reporter. Very cool. My apologies if I didn't get it
right.

I was loading a project saved on a different computer. That one is also
FreeBSD but the VM and image are slightly older. The project contains a
StackMorph with some text fields. The two scrolling text morphs were
giving me problems. Anyway, it doesn't even load. I tried the Projects
menu, and the World pop-up menu.

Andreas found and fixed a problem in the VM, described here:

The bug affects loading of older image segments (from pre-closure images)
into newer images (with closure support).

The fix is not yet in any of the distributed VMs (except possibly windows?),
but if you do not mind building a VM from VMMaker and sources, it may
resolve your problem.
