TOPIC: Two copies of the program open at the same time?

This may sound like a dumb question but I don't know the answer.
On a MAC Book Pro, how can I have two copies of the HIP open at the same time? I would like to do this when making changes to the template. One version could be open for reading and coping comments and he other could be the new version I intend to same as the updated template.

On my mac if I have the program open I can't open a second one in another window. At least I can't figure out how.

Yes you can. RIght click (or Control Click) on the first app file and rename it something else like HIP Copy 2. Now you can run each version of the app at the same itime.
