- #2: Known HyperCard Bugs
-
- Revised by: Matt Deatherage May 1992
- Written by: Dan Strnad & Matt Deatherage March 1991
-
- This Technical Note documents known bugs in the released version of HyperCard
- IIgs that may affect developers.
-
- CHANGES SINCE MARCH 1991: Revised to list version 1.1 bugs (sigh) as well as
- version 1.0 bugs.

-
- HYPERCARD EXTERNALS AND NAMED RESOURCES
-
- HyperCard's XCMD and XFCN callbacks documented in Appendix A of the HyperCard
- IIgs Script Language Guide include callbacks that find named resources. In
- versions 1.0 and 1.1, these routines don't compare the lengths of the resource
- name strings, which makes HyperCard return the wrong named resource from time
- to time.
-
- A more precise description of this problem is in Apple IIgs Technical Note
- #83, "Resource Manager Stuff." Note that HyperCard IIgs does not use the
- Resource Manager's named resource routines, but the code in the Resource
- Manager suffers from the same problem the HyperCard code has.
-
-
- PREVIOUS BUGS FIXED
-
- The two bugs previously listed in this Note--improper handling of desk
- accessories and crashing when using objects or properties of different stacks
- to externals--are both fixed in HyperCard IIgs version 1.1.
