Hi Amy
Hopefully Pete will forgive me if he mentioned this and I
simply didn't see it.
The HH.DAT file is universal to all .CHM files on your
system. So if you have Favorites in a few different .CHM files, or
had other .CHM files where you actually wanted to store the size
and placement, blowing away the HH.DAT effectively kills all those
stored settings for all .CHM files.
If you were to instruct users to delete this file, you should
be aware that you are affecting ALL the .CHM files on the system.
While it certainly "fixed" your issue, it had ramifications you
were probably unaware of or hadn't considered.
Cheers... Rick
