I have a similar issue as anon716631 (setting up a new machine for a user) and when LOADING Paratext it sits there for a full 2 minutes while it has “Looking for existing language data…” on the progress bar. This seems very strange to me - especially on a brand new i7 with 8GB RAM. Usually Logos is sluggish to load, but that comes up in 20-30 seconds, whereas PT9 is still taking 2+ mins. I’ve evn tried updating to the latest Beta 9.0.100.11 but it didn’t change anything.
It looks like I’ll have to copy the WritingSystemRepository folder over from the previous machine…
But surely we should be doing something smarter than querying the SLDR every time we open Paratext! Nudge, nudge… Scott D also reported this in Sep 2018.with PTXS-17507.
Edit: Yes, copying the WritingSystem folder from the old machine to the new SOLVED the issue for me too. I’m hoping we can automate this in future.
