ez drummer pencil note question

[Khatru]

Hey all, It's been a while. In the last month I've been using ez drummer -first time dealing with midi so I'm quite the newb. My question is regarding editing data in notes view. Occasionally, and it just happened today, seemingly out of the blue, my midi data, rather than showing up as little black rectangles suddenly turns bright green. Some notes are blanked out until I select/click in the timeline bar where they show up again. I'm sure I'm missing something. I've gone through the usersguide now twice and don't seem to be able to find the solution.

Could someone direct me to the correct page of the users guide so I can resolve this and/or tell me what I need to know.

Thanks, Dave

I seem to remember that kind of thing being a little bug that was fixed in later versions(or maybe in a later cs update). In any case, maybe if you change some video settings in Windows?
