(or the VersionedPreferences option can also be set from the option inspector).
Without specifics, I can't comment on the exact problems you've been having.
But the above setting forces the preferences file to split into a different file
for every major version.
Best to set this in v7, which should leave 5.2 with a clean set of preferences.

Can you elaborate on this issue, assuming one installs from scratch
two versions, say 5.2 and 7?
