[7.0.1451] Minor bug, run virtualized process not working from GUI

Hi everyone,
as keres1 reported in the italian board
http://forum.avast.com/index.php?topic=100420.msg802494#msg802494
there’s a minor problem in the GUI.
If I want to run a program in the sandbox, and I go under GUI additional protection->sandbox-> the button “run virtualized process” is not working, it open the explorer box for choosing the *.exe, but once selected, there’s no one opening of program.

The only way for execute only one time a program, is using the context menu by right of mouse click, run in sandbox.

I’ve make a clean installation and the problem is still.

edit:
with version 7.0.1426 there’s no problem

Yes, I tested it IS v7.1456 too, it’s not working. When you choose the file and click to the ok button nothing happen.
