Not likely to be another library. Mach is very self contained and doesnt require any other stuff.
We need to see if any VB buttons will work. On the main mach screen use the operator menu and select edit button script. That will cause all of the Vb buttons to blink. Click one of them and it will display the code in a window. Click the Run arrow in the top toolbar. That will run a VB script. You cannot do this on a newfangled wizard, they are password protected.
