[comp.sys.mac.hypercard] What does "Unexpected error 12112" mean?

jlc@atux01.UUCP (J. Collymore) (01/16/90)

I am developing yet another hypercard (HC) stack, and came up with an unusual
error message dialog box while doing some testing.  The box said
"Unexpected Error 12112" with a button that said sorry rather than "OK."
When clicking on the button or pressing return, you are dumped out of HC and
put back on the desktop.

What does this error message and code mean?  Where can I get a list of HC
error codes?

Thanks for any info.

p.s.  When is HC 2.0 expected out?
