Yes I pressed C on the grd. My KB is hungarian (which is similar to german but 7 keys are different) No probs BMS gives me the keystrokes accordingly (e.g. Orbit camera is Ö and Padlock previous Ü, etc.). Actually joy4 button is a multy fanction button and preprogrammed in x52 with different functions for NAV or AA or DF mode to DF MRM OR, When pressed in NAV it brings up DF mode and cycles through different WPN modes. When pressed in AG mode it cycles through different bombing modes. On grd it supposed to initiate NWS. This joy4 did all these up till now but now it misbehaves and by hitting only brings up the AA missile page in NAV without cycling and the same on grd after landing, but without NWS. So fare works only what you suggested. Most likely somehow DF comes into it but I do not know how come. I tried to program same with different button but no change. The bug somewhere inside. Many thanks ICER.
