There was a delay as my RPi SDCard got corrupted which I am quite sure was de to he Compress Charts
In my case the MBTiles chart that WAS working fine in v5.0 is about 20GB in size. When I click on the Compress after some time the window didn't refresh and was not closing so I pulled the power. On reboot kernel panic due to locked SDCard.
It might pay to add a second prompt on Compress Charts
defaulting to No
In any case v5.2 is great apart from the annoying regression for me with my MBTile chart. I construced from SAS Planet and confirmed it views with MapTiler Desktop
Free Edition. It's such a pleasure to be able to make your own charts and have them used in Open CPN
If this can be made t ofunction as was under v5.0 it would be great.
AllLake_7 is the chart file giving some issues.
I took what I could from the log as below:-
