Well we have looked at this issue at length, and its difficult to solve. The Windows operating system was never designed for applications like Switch which has both GUI and command line aspects to it, and as such we do not know yet how to block the command line when running Switch conversions. A command-line only program does not have this problem, but since Switch is hybrid software it does.
We are determined to come to some sort of solution that can make things easier for other developers, so all we can say is to bear with us while we examine the issue. If you have suggestions to help us out in this sort of thing, feel free to pass then on to tj[at]nch.com.au
