Flight deck 4 users - advice please.

Hello- Just got Abacus' Flight deck 4 and I see there is a free update to FSX. If I use the update, does Flight deck 4 work on both sims or isit transferred to FSX and that is the only sim it works on after the update?It would be nice to have someone who has done this update confirm the position please.Also, where can i find out if the Hornet has the ability to use auto pilot -I can't see it on the Super Hornet, and on the ordinaryone, the alt;hdg and IAS dials don't have the ability to be changed .Maybe I'm missing something?Thanks in anticipation
