I should also mention, I tested this with the latest git as of yesterday (8/30/2013) and the bug is still present.
I'm finally getting around to digging into this a little bit, would you mind seeing what happens permissions-wise on Windows for the user's "Application Data/MakeMusic" folder? I suspect that it's setting world-writable permissions (exclusively) and inheriting permissions from the parent folder that allows the user to continue to read the files.
