Tough luck.  It looks to me like HyperCard opens every stack read-write,
which means exclusive access.  This leads to several other anomalies, which
annoy me to no end: It's not possible to browse a stack which is locked or
is on a write protected diskette.  Browsing any stack causes my backup
utility to back it up again.

Apparently, this is because of the automatic save feature.  Apple, why not
go ahead and open for browsing, and just warn the user that updates can't
be saved, if the file isn't available for writing?  And why not provide a
HyperTalk command to open read-only (as in Browse)?
