IF10 preview version [sg11] is available in the New Builds section and is the release candidate for the commercial version [sg]. If you want to try it now there's no worries when [sg] comes out as it will simply install over and carry on working as [sg].
Check it out for better weather and thermals, neater weather and settings pages, user interface for setting up other apps to start up with FSX or IF10, and a bunch of bug fixes.
Thanks everyone with all the help and suggestions and spotting all the bugs.
