The most common problem that HyperLaunch users encounter is adding new applications. The new "Add" button makes a text-only button with the name you give it. You can add an icon and move it around freely. Automatic icon linking should be in v2.0, assuming Apple makes some documentation for this sucker.
If HyperLaunch keeps asking you where an application is, use the "Paths…" icon to make sure the search paths are set right. If not, reset them. If that doesn't fix it, make sure the button's script and the application name agree.
Everything else follows the HyperCard metaphor. If you have questions or problems, contact us at one of the following addresses:
