Script will not complete if run in a scheduler - WOE

[Jchiam]

I have a script that runs fine if it's manually executed. However, once placed into a scheduler, it dies when it gets to the 'mouse right-click on file' stage of the script.

I browsed through the forum and figured out that it didn't work cos it was interactive. So, I used a scheduler called Splinterware's System Scheduler which has the ability to lock and unlock a computer. The train of thought was:

1:00 PM Unlock computer

1:01 PM Run script

1:02 PM Lock computer

Geez. Sounds so easy. It still died at the mouse right-click stage.

Any insight would be greatly appreciated! I am sure someone out there must have bumped into this wall before...

Help!
