More on Large Files:
I think I've found the point at which WavePad chokes. I had occasion to work on a two-hour file today. I couldn't "play" any sections where I placed the cursor beyond 1 hour 41 minutes into the program, unless I placed the cursor EARLIER than 1:41 and let it play through uninterrupted.
Actual editing and applying effects anywhere seemed to be unaffected by this mystery "wall" -- it's just that I couldn't hear what I was editing.
