Closing window in PAC Display

I would like to use an event (timer timeout) in my Opto Control strategy to close a window in PAC Display. Is this possible?

Here is what I am trying to do:
I have a window that has several variables from my strategy displayed. Some of those I want editable by the user, but be password protected. I know I can have those variables editable, but I can’t find a way to password protect the editing. So I created a duplicate window that is password protected. the password protected one allows editing, the other doesn’t. But then at the expiring of a down timer, I want the editing window to close (so it can’t be left open for unauthorized editing).
