Hello

When I drop an Instance of a PasteUpMorph into the ProjectView window
of another project I get the error message below.

This is in a 5.1beta image but with the updates applied so that it is
similar to the release image (I assume). This also happens in 6.0alpha
most recent update but not allways.

Any suggestions how I can fix this?
Is a subclass of MorphicModel a UniClass? How can I detect a UniClass?
