Hi all, it seems that since SU 6 my key binds for F keys aren't working any longer (and possibly other keys, e.g. the space key). I tried in the Maddog and in the Ifly Max. When assigning whatever function to a "normal" key it works, If I try same function with F keys it wont. First supspicion was Chaseplane, but it still doenst working after disabling Chaseplane.

Anybody else seeing that? Or maybe a known issue already ?

Thank you !

I have checked and confirm this - the function keys and space key (and maybe others) are no longer being received by FSUIPC via the SimConnect interface. I have checked the documentation for the valid 'input strings' for keys ( https://docs.flightsimulator.com/msfs2024/html/6_Programming_APIs/SimConnect/API_Reference/InputEvents/SimConnect_MapInputEventToClientEvent_EX1.htm) and these have not changed, so this seems to be an issue with SU6. I will make some further checks (and see if the 'input strings' for MSFS2020 are valid) and report to Asobo / MSFS.

I have checked further, and it seems that MSFS2024 is now using the same key 'input strings' as MSFS2020, or at least for the function and space keys (and maybe only when using the MSFS2020 SDK).

Can you try the attached version please (7.5.8f), where I have reverted to using the same key input strings for MSFS2024 as used in MSFS2020.

Attachment : FSUIPC7.exe

I will also clarify this issue with Asobo.
