I am using Windows 8.1, and lacking knowledge of how to explore what
we once called the Start menu, I just type in app names to run them. I
actually missed the existence of the VAC Control Panel. I will look at
that now to see if I can make that easier to use as well.

HI,
I have no idea about your code, but on my system with VAC 4.10 it
works as expected. But I think that this version is quite outdated so
maybe I definitelly should update and test it again. Anyways as a
future request, it would be great if you can also name fields in the
application control panel. But still, good job.
