Hi ristra
If you would like, I'll be happy to test one of your .CHM
files on my Vista install. To my knowledge, there is nothing unique
and specific to .CHM files created using RoboHelp that would
preclude displaying under Vista. I do know that if you are using
one of the features that require the HHActiveX.DLL file (Browse
Sequences, Glossary Tab or WebSearch) that the .DLL will need to be
present and registered in order for those features to work
properly. But all that would cause is for the Glossary tab to be
blank or the Browse Sequence bar to simply not appear. I've never
known this to cause the entire .CHM to fail to display.
Are you absolutely certain that the .CHM isn't on a LAN?
Hmmm, in reading your initial post, I do see where it appears to
display just fine under XP.
Also, how did you obtain the .CHM? If you downloaded it from
a web site, maybe it's simply being blocked. Then again, I would
think it would behave the same way regardless of the OS. Obviously
something is amiss.
Wish I had something more or better to offer here.
Cheers... Rick
