I just installed RC 4.3 and ran into a problem for which I have not found a solution so far. I see the Radar Contact Window and can move it around just fine, however it doesn't recognize my keystrokes. For example, if I press '1' to request a clearance, nothing happens. The windows stays the same, the frequency won't get changed and I hear no chatter.I already tried all predefined keystrokes, checked for interference with FSX keys and all that. I don't get it done.I have the Options FSUIPC multiline display window and Hide all single line messages checked in FSUIPC, just like the manual says.Can anybody help me please?Merry Christmas to all of you.pepeI have installed:Windows XP SP3FSX + AccelerationRadar Contact 4.3FSUIPC 4.4
