Sorry, I have not been keeping up with PGV releases. I am still at 4.1.6. It looks like that is almost a year old already. I have to upgrade and see if the CGI interface still works...
I should also admit that I never got the merge feature working as well as I wanted. Make sure you make a backup before merging.
Thanks, John. I don't think anyone checks GDBI before releasing a new version of PGV. The interface was broken the last time I upgraded, which was around version 4.1.6.
