Screen freeze in both 32 & 501 squadron campaigns

I'm working through the 32 Squadron campaign to fix the compatibility problems with the latest release. So far I've found two different issues:
On the first mission when the bombs hit Kenley it would cause a launcher.exe crash. There are a number of stationary vehicles there and I couldn't identify any particular type that was the cause of the crash. So I've thinned out the vehicles and this avoids the crash.
The second issue affects several of the missions - too many barrage balloons will cause the game to freeze when you come within range of them, or switch view to any object near them. For me the max number of balloons is 7. FMB will freeze if I try to add more than 7 balloons, or zoom towards the balloons in an existing mission. The problem affects the winch anchored balloons - Aeroanchored.Balloon_winch_UK1 - but not the free barrage balloon Stationary.Balloons.Barrage_Balloon_Uk1. So I'm replacing these in the Dover balloon barrage.
The FM changes also seem to have affected time lines a little so I'm tweaking waypoints to compensate. And the performance improvements of the latest release sadly don't appear to be sufficient to remove the worst stutters from some of the plane-dense missions so I'm reluctantly thinning these out.
Hopefully will get all this completed in the next few days and will post the revised mission files to airwarfare.
