Access violation while displaying the world map

[K5WW]

Every time I display the world map I get an "Access Violation" message. See attachment. W10Pro.

When the world map is not visible there's no problem. It can be hidden behind other windows and everything will work fine for hours and hours.

But as soon as I minimize or close those other windows (and the world map comes into view) the problems begin.

The only way to get the message to disappear is to close Swisslog with the Task Manager. Clicking "OK" brings up the same exact error message, over and over again.

Any suggestions?

Thanks,

Erik
