Hi all,
I have just installed MS Help Compiler Workshop v4.03. When I go to
double click on either a .hpj (help project) or .cnt (help contents)
file, I find that both are not associated with HCW as they should be as
part of the install. No real dramas, I go to View --> Options --> File
Types, and see that the file associations for Help Project and Help
Contents are in the list (to me this means that they are in the registry
- yes?), just not associated with HCW. I do that, fine, it works OK.

Next time I reboot, I notice that the file associations work, but the
correct icon is not displayed for these file types. Doing the
abovementioned process but just changing the icon to whatever it should
be works fine once, but a reboot seems to make the problem re-occur.

I know this is a trivial problem, and hey, the file association works so
why am I worried? But to me this indicates a problem of some kind,
either with HCW, or (god forbid) my registry. The latter is unlikely
(I'd like to think) as the PC is new.
Any ideas?
Thanks,
Regards,
Sean...
