This sounds rather like a problem I had when I first used ST V/286.
In my case, it turned out there was a bug in the cursor management
methods that caused an invalid image to be saved.  They missed the bug
because these methods are never used if the cursor is managed by a
mouse driver.  (Yes, I'm a non-mouse diehard.)  I know you use various
mice, but is it possible that you ran your initial tests with no mouse
driver installed?  That would leave you with a nonusable image.

They sent me a fix (it's a painfully simple bug), but it's pretty old
and I don't even know if it applies, so you should probably get it
from them directly.  And if it really is the same bug, you can avoid
it just by always booting with the mouse driver installed.

Digitalk seems to have a pretty responsive support department.
Probably you're thinking that doesn't do you much good from 7 or 8
time zones away.  What you probably ought to do is send mail to their
Compuserve account.  I'm afraid I don't know what their account number
is, but you can send mail to Compuserve at xxxxx.xxx@compuserve.com,
where xxxx.xxx is the Compuserve account number, with the "," changed
to a ".".

And what *they* ought to do is monitor this group.
