I checked since I made the post last night to the thread "viewing web pages
correctly in a browser", and all versions of NoteTab use the same commands to
view a document in a browser.
If there is a difference in how the relative URLs are interpreted, it is
because the directory structure really is different, there is a naming
difference, (capitalization is a big one here, once I went to one of my sites
where absolutely nothing was working, and somehow, all the files were
suddenly named with all caps. That weh-host, by the way, is now out of
business, even on my hard drive, I once had a problem with a setting changing
the names of my files for me (and I'm not sure what I did.) )
To test your directory structure, use the menu commands Document | Insert
Html Link/Image, and browse to the file you need to link to (or use as an
image.) Note Tab will automatically insert a link that is right for your
current directory structure.
If, in viewing, you get another browser besides the one you wish, you may
change that by going to the NoteTab Options dialog.
