Re: Screen Widget script handling enhancement

[David E Jones <jo...@hotwaxmedia.com>]

Don't worry about doing anything about the transaction thing. I was  
just meaning that when you skip the service engine you lose the  
additional transaction control (new transaction, timeout, etc), but  
for this it really should be needed.
