I've used OpenCPN
for some time and truly enjoy the program. I was reviewing some routes I created when I got a message indicating the program stopped running then the screen
colors changed to what I can best describe as a negative view. For example, the ocean is now black with shades of gray for shallow areas near shore, land is dark brown. Printed words are now grey in color and very difficult to read. All the features are there but the program is unusable because it's too difficult to view the screen
I was using version 4.8.4 so upgraded to 4.8.8. The download was successful but the screen colors did not return to normal. I tried closing the program, then restarting it. I also did a complete computer shutdown, both actions to no avail. All other programs on my computer run perfectly with correct colors, brightness and contrast. Any thoughts as to why this happened and how to fix it?
