Hey Pavel, I am using a MacBook Pro with Lion 10.7.5.
The steps to recreate the crash are as follows:
Delete a waypoint (waypoint list disappears)
Start Open CPN
Click on Route Manager Icon
Click on Waypoints Tab
I am unable to edit any waypoints because of this issue.
Also, I notice the Route Manager is extremely slow to load (like 7 minutes). I am running my laptop
on a SSD, which is usually lightening fast except when loading the Route Manager. I have 1200+ waypoints and cannot imagine why it takes so long to load them. After I edit a waypoint (whether I make changes or not) it takes another 5+ minutes before I can do anything.
I tried looking to see if there was a limitation on the number of waypoints OpenCPN can store, but the web site must be down. I keep getting a bad gateway error.
I'd be willing to load up the beta version and mess with it.
