Some time ago, I posted a desperate plea for help with providing help for
message boxes via the help hook (the only possible way to do so).  I did
everything according to the documentation to no avail; I could not get the
"Help" button to work.

Well, the documentation was wrong and has been since OS/2 1.2 (both IBM's
Programming Guide and MS's QuickHelp overviews are incorrect).  They state
that, if you are going to use a help hook, it should be installed PRIOR
to creating the help instance, since it too installs a help hook to perform
its function.  However, if you assume for the moment that it uses the
WinSetHook() function to do so and look in the docs for that, you'll see that
the call installs the hook at the *head* of the hook chain.

That means, for those who don't already see the problem :) , that if I install
A and the HM installs hook B afterwards, the hook chain is B->A; but the HM
never calls the next hook!

When I moved the WinSetHook() to after the WinAssociateHelpInstance() call
everything worked fine.

You would think that *someone* *somewhere* would have found this doc error,
but *AP*p*AR*ently not.  IBM, please fix this.

Cheers,
Q
