on two places as far back as I recall.
office & home (not running concurrently)
office mac & office windows (not running concurrently)
only one can complain?
Not arguing for or against, but I thought that it was always that way.
What was your use-case for using both at the same time? I assume it was primarily for testing.
One on the server, for testing same-machine timings as opposed to LAN client timings.
Two machines for debugging, very useful in a script chain or for evaluating things at different levels at the same time.
The wording you quoted matches very closely with the license for the rest of the platform. But I agree, those are good reasons to have 2 copies running simultaneously. We have a site license, so it affects us a little less, because we always have extra connections or licenses available.
I would love to see a developer license that allows us to more appropriately test, with both the number of simulated users, and as you mention various stages of script completion.
I don't care about the full enchilada, I wish I had a Filemaker Debugger Client letting me only go through scripts and evaluate stuff in data viewer. No browse mode, only layout and preview mode. Or a browse mode in which the records you create get deleted after an hour automatically. Maybe a way to debug find mode. Free, no licenses. Wow.
I've never ever produced useful business data through FMPA. Its client capabilities are useless for me. It's my tool for creating, never been a tool for using.
