Hi,since I installed the "big" 737's, I can't use the stairs anymore. The key-combination strg, shift and e, which I used together with concorde nose doesn't take effect, other combinations are the same. How can I reactive this feature?Thanks Kai

You should check the PMDG own key commands, there were several combinations and I had to delete some to get my airstairs working with my preffered keys, because PMDG commands override the FS ones.
