CH Yoke le....... Hat switch

Hi Ha allUsing a CH Le yoke(Usb), suddenly discover 'hat sw' refuses to work in flight mode, although the Keyboard keypad commands do.The reason I mention Flight mode, is that it works fine in 'Slew Mode' which I have been using alot lately in connection with the scenery design I am doing.I have looked in the FS2002.cfg, gone though all the options in the Assignments menu, checked the calibration, deselected/selected joystick in the controls menu. I have rebooted pc. I have a PFC.ddl installed for a thottle console unit I use and a FSUIPC.dll, and can not detect anything that may becausing this glitch I tried uninstalling any recent sceneries from the 'Scenery Library' menu. and this and allother attempts have failed.It is properly frustratingly simply I don't doubt, but I would really appreciate some help as I am pulling my hair out!!!RegardsDave
