I wonder if this is related to a problem I've noticed with
Workbench-driven disk copying:

While demonstrating my Amiga A2000 to a friend (who later bought an A2500),
the question came up, "How do you duplicate disks?"   "Simple"  I told her,
"You can either use the keyboard-entry command, OR you can do it this
really convenient mouse&icon way..."  I then double-clicked the "DiskCopy"
icon in my System drawer, and followed the resulting advice on how to
perform the diskcopy:  inserted original disk in drive, single-click-selected
that disk's Workbench icon, and then selected the "Duplicate" Workbench
menu item.  A requester opened up, with a cheerful countdown of all the
tracks from the original disk that were were being buffered up in memory.

Since the foregoing had adequately demonstrated the proceedure, and I really
didn't want another copy of that disk, I clicked on the requester's "Cancel"
gadget.  Kaboom!    "This is what we Amiga users refer to as a 'visit from
the Guru'", I explained.
