The Problem
-----------
In order to fit on an 800K floppy disk, HyperCard 2.2 is shipped as a
compressed file. The HyperCard 2.2 installation procedure doesn't make the
Finder aware that the application that's been installed is HyperCard and
the Finder doesn't add it to the Desktop database. On systems that already
had HyperCard, there is a HyperCard entry in the Desktop database, but it
points to the older version. Thus when a stack is double-clicked, the
older version of HyperCard is launched. Finally, systems that have never
had HyperCard don't know what icons to attach to stacks.
The Fix
-------
All you need to do to teach the Finder about the new version of HyperCard
is to open the HyperCard 2.2 folder that is installed. (Few customers will
have any of these problems because the first thing most of them will do
after installation is look to see what is in the HyperCard 2.2 folder.)
Then their stacks will find the correct HyperCard, and under System 6 their
icons will show up.
Under System 7 there's another wrinkle. If System 7 sees a HyperCard
stack, it will cache the appropriate icon until the Finder is restarted
(restarting the computer will do this). If it sees a HyperCard stack
before an entry is made in the Desktop database for HyperCard, it will use
the standard document icon. Thus under System 7, if the Finder sees a
stack before it knows about HyperCard, it will give all stacks the standard
document icon until it is restarted. If you see this problem, open the
HyperCard 2.2 folder (to show HyperCard to the finder) and then restart the
computer. Note that this will only happen on systems that had no prior
knowledge of HyperCard or Player or systems that had HyperCard deleted and
then had their desktop files rebuilt. Unfortunately, the Finder will see
the stacks in the HyperCard program folder before it gets to HyperCard, so
these systems will get the icon problem and you'll have to restart your
computer to fix it.
