Applescript timeout when screen is locked

I am getting an AppleEvent timed out error when my Applescript is running and the screensaver turns on and locks the screen. The applescript completes the current operation and when trying to do the next Finder operation it does not proceed but waits and times out.

I cannot increase the time-out time limit since I will not unlock the screen at all. Is there a way to ignore waiting for the screen unlock or some other solution to this?

Thanks in advance.

Other than this I cannot think of anything.
