Stars 1.3 works great w/mine.

This works file too.

No problem here.

The problem with most of them lies with your mac being a Mac+, and not with
your owning a Dataframe 20.  I have a DF20, and have had no problem with 
the stuff I listed.  Also, the symptoms (crashes) you described are things
that the *mac* is doing, and not your drive.  Basically, many of these
programs (like Stars) write DIRECTLY to the screen.  If the screen isn't
where they think it is (a Mac+'s screen is in a different place in 
memory from a 512K's screen), they will wind up writing over something
important in memory, causing a nasty crash.

Also, there's a neat program (actually, there are several of them) that
will test desk accessories w/out installing them into your system file.
You might want to check these programs out (they're either public domain
or shareware).  The one I've come across and use is DASampler.

And lastly, there are a few KILLER DA's out there.  Most notably Jclock,
which will thrash your hard drive.  I believe that Lockout is also
one such program.
