Hey Dan - sorry to be coming right back again. After I got the app moved over to where I could see it, I tried to click on "Select a flight plan" and the button depressed but nothing happened and then the app locked up. Tried this several times with different buttons like "Option 1 & 2" but same thing happened. Then I tried pressing "Update" button and got a message saying i needed Net Core, so i downloaded that and the app still locked up. Then I saw FAQ #16 and changed the "Auto Updates to "0" but that didn't help either. I noticed that the "Connect to FS" is grayed out so was wondering if maybe something is not working with Sim Connect and that might be the issue?
Okay, since replying to this post earlier I've now deleted that reply
If you download the Interim Beta version (3.19.6) just posted at the top of this forum... run it and then right-click the picture of the aircraft on the PF3 main screen, it will ask you if you wish to reset all the previously saved PF3 display window positions. Just select Yes, then try PF3 again. Everything should hopefully then be back to normal
