lazy/smart prepare?

Don't forget that we have unsafe scripts that can pull their data from sources other than Filter Forge -- see our Real-World Clock example.

Yes.

FF has two layers of protection, both configurable in Tools > Options > Scripts.

First, execution of unsafe scripts is disabled by default -- no unsafe script can execute unless this setting is enabled. If you want safety, you should never turn it on.

And second, when you try to open a filter containing an unsafe script, FF asks you for confirmation. If you want, you can configure it not to open such filters at all (but be advised that copying such filters directly to My Filters folder bypasses these warnings.)

Additionally, all script components are set to 'safe' mode by default, and we don't accept filters with unsafe scripts to the Filter Library.

BTW, have you read the last section of our Beta Stage 4? It contains info on unsafe scripts -- scroll it to the bottom: http://www.filterforge.com/download/b...pting.html

Right -- the checkbox cannot be bypassed this way.

Also, you can't write a script using unsafe functions and then turn it into a safe script by hacking the XML to set the 'safe' property to TRUE -- this won't work, the unsafe functions won't be available.
