Its changed slightly since i posted that, sam suite is showing 2.1.0 (with developer 1.0.1 which I installed after i initially posted), I only replaced the 3m file from this post as that's what im using.
In Wed just selecting, as the active object WED crashes to desktop.
The other day, i had tried placing a safegate, then edit the resource to point to FMT which crashed the sim too, but now its loading in the sim doing that, I must have miss typed the asset name or something.
I replaced the above 3m file in the Custom Scenery\SAM_Library\dockings folder and it started working.
Right now doing it as i type this with the 5m, its just wed that is crashing repeating those steps, until I replaced with the above file into the SAM_DeveloperPack folder.
