I find no adobe folder in preferences. But i do find::
Adobe Dreamweaver CS3 Prefs
I tried trashing both, but it did not fix the problem. All it did was ask me to pick another browser.
Unless there's an easy fix I won't bother reinstalling. Regarding the comment from the Adobe salesman, I don't use DW enough to warrant buying a new version for $200. DW 3 works fine, it just won't load the help menu, which also works fine when I load it in Preview.
I know enough about computers to opine that there is probably a solution to this without having to reinstall. Like renaming the help file, or maybe someone telling me where to place it in the file hierarchy. Actually, I tried placing it in 4 other places. No luck.
