it seems to happen on various projects but it feel like it only does it when it wants too. (i know it's not the case..but it feels like sometimes it works, and sometimes it doesn't). what i am trying to do is copy some midi notes from the piano roll of one track and paste them to the piano roll of another track. i COULD show a screen shot but it really wouldn't show anything... it is just an error message saying "function not supported in current window". i am taking that to mean "no pasting allowed". another issue that may or may not be related is sometimes a set of midi notes will not make noise with one instrument and will with another. I'm perplexed. I'm sure it's something simple but i've tried lots of things... it's almost like a glitch.
