A side effect of this issue is that the Print option (menu
or button) is disabled after the error message ("Cannot
focus a disabled or invisible window"), and the only way to
recover from this is to "unhide" the diagram explorer and
model explorer windows, then exit the application.

It seems to be an issue that fails when a refresh routine is
being called, and there is an exception that stops the
processing of the rest of that refresh, so buttons in the
toolbar, and options in the menu do not get enabled correctly.

I have the same problem.
It becomes impossible to work with StarUML anymore.
