Since the recent (couple days ago) update to Charts (Windows Desktop), Charts will freeze (moving map stops moving; pinned charts can’t be opened, etc.). In order to fix it, I have to close Charts, re-launch, and sign back in…a big pain. Exact setup with prior version never had this problem!
Please update to the latest version 7.4.2 which was released just minutes ago and let us know if it works better. If the app doesn’t prompt you, you can get it from Navigraph
