My company has recently ported an application from Delphi 5 to Delphi
7. Everything works fine, except for the context-sensitive help.

When calling up the context-sensitive help for a control (e.g. by
pressing F1), the Overview page of the help file (.hlp) appears
instead of the small yellow help window for the specific topic.

I have created a trivial test application with a single edit box, and
an associated help file. The help context issue is reproducible in
this test application when it is compiled with either of the following
compiler options: 1) Build with runtime packages; 2) Use Debug DCUs.
This test application clearly demonstrates that this is a Delphi 7
issue. The issue is unfortunately not resolved by installing the last
update that Borland release for Delphi 7 enterprise.

Unfortunately, our application *must* be built with runtime packages,
since a core feature is the ability to load UI plug-ins, which we
implement as DLLs.

Has anyone seen this issue before, and perhaps has a workaround?

More information:
This issue manifests when the help type is htContext (i.e. we're
looking up each help topic by ID).

I can provide a trivial test application that reproduces this issue.
