I guess you need to zoom in/out. There's some governance that checks zoom level and fixes it. In some old versions of RetroDebugger there was a bug that could set zoom level to 0, and thus modifications by multiplication anyway always give zero, now it should reset to some normal value when this case is discovered on zoom in/out event. Let me know if that's the case. The quickest fix if zoom in/out does not fix the issue is to reset settings.

Zoom did not help. Then I used reset all setting to factory default and the editor comes up black again.

That is interesting. Please check what zoom level value is shown in this menu? Also, please try to pan the screen (by pressing space). There was a bug indeed that may cause to move screen out of bounds, but that has been fixed and resetting settings should fix that. Anyway, if that does not help I'll prepare a debug version for you to dig more into this.

Space did not help.

Reset zoom option added in 1084cb5

Please check this version (for macOS), in VIC Editor menu there's new option "Reset zoom", please confirm if this helps.

I can confirm the reset zoom fixes my issue. Thanks a lot!
