Hi Peter,
No, nobody at my company has tested this specific problem
with other HATs. It's unfortunate that we are not going to see this
through, especially after all the work I put into it.
Yes, I did have the programmers look at your site (nice site,
btw!), but they said it's not what they're looking for. They want
to be able to call the help, show the help, have the user go back
and forth between previously viewed pages and have the help always
in the foreground (sigh!).
