I always use the default aircraft to try out new apps to keep things simple. Here's a strange one.... After contacting Clearance and receiving altitude, squawk, etc., the hydraulic systems in the 737 no longer function (can't raise or lower flaps and gear). I've tested it out and it's repeatable... before contacting clearance, flaps raise and lower normally - after contacting clearance, the flaps freeze in the raised position. Could PFE be sending some obscure instruction through WideFS? I looked in my FSX key assignments and no hotkeys are assigned to the hydraulic systems.
