Hi Pete,
In P3Dv3, I had CTRL+X set up for the open close RCv4 simconnect window. This was set in RCv4 itself where you can programme a command to open and close the window. In the FSUIPC menu in the Hot Keys tab, I had "Toggle FS Display Window On/Off" set to CTRL+X also. Finally I also had AdvDisplayHotKey=88,10 set in FSUIPC.ini, which I think correlates to CTRL+X. I'm not sure exactly which one was opening and closing the window but I'm happy to test by turning each setting off one by one if that's helpful.
Yes, in P3Dv3 it did. For example if I had the window turned off during the cruise and then I received a request to contact the next sector the window would pop up.
I used to do the same but then I started using MCE and the developer of that suggested running both RC and MCE on the sim machine to prevent any latency issues. Not using MCE yet on v4 though, so I don't think this is interfering with the window in any way.
Thanks again,
Dominic
