I am trying to get a simple VB script to activate as a test in "ApplyGUIScript". My script will work if I run it by double clicking on the script file in explorer, but will not run if I drag and drop it into a Gui Session. There appears to be no response from the Gui, not even an error message.

There is probably something wrong with the "msscript.ocx" file on your machine. You can download the "Script Control" from the Microsoft website to correct it.
