Do Virtual Folders refresh upon changes to their Source?

Thanks for your reply, Yuri.

As I'm not a programmer, I'm curious how the various objects pop out
in response to mouse-overs.

Is this a function of Java, Javascript, or some other scripting language?
or, not a script at all, but some other technology?

When I installed the Clipboard Mgr, what a delight!
So simple, yet powerful - love the Drag & Drop,
& the support for the necessary file types.

Bravo ! =D>
