Well, I persevered and finally got through this puzzle. But on my second play through, I'm giving up and using the 60% screen solution. From what I read, the bug is specific to Windows, but not all Windows. Who knows - it went like a snap when it actually worked!
I'm finding I have to use the 60% screen size on getting the little red bugs
No luck there yet although I can at lease move them around in the smaller screen size. They were completely unresponsive in full screen.
traveler, did you ever get the red bug puzzle?
