I don't understand:  You're correct that ProDOS 8 doesn't need the
AppleDisk5.25 driver, so what does this have to do with ShrinkIt 2.1 and P8?

That's sounds very odd--it's always worked fine for me, and I've never
installed the UniDisk3.5 driver (since I don't have a UniDisk 3.5).  From
very limited information, I'd guess that the application had a problem where
it would use data in the wrong bank under certain memory configurations--in
a delicate state like that, adding or removing any driver, DA, etc, can make
or break the application.

It bothers me a little to see anything written off as plain "buggy"--what
problems are you referring to, and what is your source of information?  The
only problem I recall at the moment is that it returned incorrect write-
protected status under some conditions.
