Okay I've read previous topics where Studio slowed down due to slow server or software that connects it to the server.
However my Studio isn't connected to any server, my TMs are on my local computer and I even disconnected my MTs services to see if it helps. No, it didn't. Confirming a segment and moving to the next one takes about 10 seconds with the message "Generating Preview" at the bottom bar being displayed.
Any solutions?
