Is there any way in screen to schedule time a .stml file 
runs.

Martin, to answer question best we direct you to the 
documentation.  Click on the Start button and click on 
Screensurfer Documentation.  When the main documentation 
page is displayed, click on the "Basic Scripting" tab.  
From "Basic Scripting", at the top of that page under "Page 
Links" click on the "Time driven TESections" link.  At that 
place in the documentation, how to schedule sections of 
code to run is explained.  Please let us know if you need 
further assistance.

Thanks I have seen it and I will play with it and I think I 
will figure it out.  Thanks again.

You are welcome and happy "surfing"!!!! :)
