We discovered today that the Search function is not working
for a compiled Help build. The Search feature worked on builds done
in the past (I tested this with a completed CHM Build done 6/2007),
but no longer is functioning on builds completed today. Any search
returns a "No topics found" result.
I see that others have experienced this same issue recently.
We have the TC Suite, recently updated to include Acrobat 9.
So far, this TC Suite has been nothing but a headache for us
here in my company (but that's another story entirely).
