Hey thanks Carl - it's back! It may have been what you said, but the strange thing is, I have two legitimate copies of PD9. One on my home computer, and the second on my work computer.
They both did exactly the same thing at about the same time. My home computer started this Sunday; when I got to work Monday, that copy was doing the same thing.
Maybe it was what you said, but strange as it seems, I tried it twice after reading your post, the first time nothing active, i.e buttons etc., showed up in the Magic Music window. I closed PD9 and started it back up, opened a project and it didn't work. Close PD9 again and opened it and every thing was there just like always - really weird.
Thanks for your time and help,
Tangle
