Many of us have been bitten by Scroll Lock - glad you are all better. One of the strengths of these Cakewalk user forums is that most 'gotcha' things have been discovered and discussed by multiple folks, so that simply posting details on a given issue will usually result in one or more folks helping to resolve the issue.
I certainly have been assisted on countless occasions by reading of the solved misadventures of others on things like Scroll Lock, or increasing a buffer size, or doing this, or not doing that, etc. It is precisely because I have been helped directly and indirectly so many times that I try to give whatever assistance I can to others with issues. :)
