[RWP] Input changes for all tracks

[Mohamadreza Ghanbari]

Hi

When I set MIDI mapping for a track using the context menu that comes
with the application key, all tracks change to map to the same track.
This doesn't happen when I adjust input settings by locating the input
property of a track using JAWS cursor and click to popup the context
menu. I'm using reaper 4.54 and as one of you friends said, before
pressing the application I have to press ctrl+up errow to be able to
access the context menu.
Any ideas?

Thanks
