I use an Oregon 450 with GB Discoverer Premium. I have the latest version of Basecamp running on a Mac Mini with Yosemite installed. Base camp constantly crashes when zooming and moving the maps. Some of the sections of the maps only show on half the screen and the other half is the standard road map.
I have tried installing and reinstalling Basecamp but without any difference to its performance.
What is wrong and how can I correct it?
