For the first time with the new KHP I encountered the old black ghost that was quite common in prior versions when trying to sweep a fast pace song. Today I was working with a rather peppy polka and was fraught with ghosts at one point in the song. By re-arranging word placement was able to get it down to one persistant ghost that would not go away no matter what. I was using 26 point Arial font. It occured to me that if I reduced the font size one notch to 24 (still a very respectable size) then perhaps the program would have that much less area to draw, and guess what? Worked like a charm, and worked on another even faster polka I was having a problem with. Not a bad trade off to have a clean song.
Thought this worth passing along. Hope it helps somebody. (with my luck it's already in the manual somewhere
Take care,
George
