A few questions about the FBM, (no FMB forum?)

[bounty]

Tried my luck on SimHQ but no luck so far.

I've been enjoying the FMB over the weekend but have a couple of questions you might be able to answer for me...

1. How do you get working search lights? I can get them in the mission but they don't do anything, (regardless of the time of day). There is a set target button in the properties but it doesn't appear to do anything
2. Is there an air-raid siren anywhere?
3. Are there any triggers in the FMB?
4. Ai Actors, what do they do and how best to use them?
5. Any way to get ai aircraft to taxi to add a bit of atmosphere to airfield/missions

Tried the following to get the searchlights to work
Added a flight of german bombers to fly directly over the searchlights, then added some flak to see if it would fire and it did. Searchlights however just sit there doing nothing and with the light off. Also tried 700ft, 1000ft & 2000ft altidues for the bombers. Flak worked at all heights but still no searchlight. Times of day tried 21:30, 23:00 02:30, same result.

I wonder if you need the anti-air AI actor nearby to get it to function properly? Perhaps that's what the AI actors are for

Thanks in advance...
