Here is what I use to get around this issue, while maintaining some semblence of security.

Install the free ClickYes. Running this all the time will totally defeat the security. To maintain some level of security, I use this (ugh) BAT file.

echo %echo% off
set prog="C:\Program Files\Express ClickYes\ClickYes.exe"

Echo %prog% - Starting
start "Run Async sam window(/B)" /B %prog% -activate
sleep 60
Echo Stopping it .....
%prog% -stop
Echo All over now...

Run the BAT file, then start your perl script. If your script takes longer than a minute to run, adjust the hard-coded sleep time.

You could easily incorporate the BAT file functionality into your script. In my case, I was not running a perl script - it was an Excel macro written by someone else.
