I'm sorry to ask this, but what causes this error message? I find it happens
upon loading help patches for externals (about 50% of the time), for example,
and it's not limited to any one externals author.
Lately, I've found it best to use the external's source code as documentation,
because of this problem. But if I can get the help system to work, it would
probably be easy to just load the help patches.
