Hi James,
Thanks for posting!
The Method Classic screen designer was originally developed some years ago now, when Screen Resolutions certainly weren't what they are today. The result of which is this occasional 'Ghosting' you see on modern Hi-res Monitors.
The development cost of going back and re-writing this would not be insignificant, so to be completely transparent with you James - this is unlikely to get a patch, especially considering Method:New already handles this much better.
For what its worth - I still customize in Classic myself relatively often, and have found that if you collapse sections that you arent working on (by clicking the Hide button in the top right of every section), the Ghosting effect happens much less often.
Thanks James
