Peggy, I had both 5.0.x and 4.1.x on my machine at the same time. It’s hard to do a search on version numbers here on BOB, because the search engine includes the period as a “break” character – so it breaks 5.0.x into 5 and 0 and x – and further, only non-common words of three characters or more are indexed.
So, I tried a search on: two versions – and here’s an old topic from the Listserv days that tells you that you can do so, and how to get it.
