Been using FSUIPC and P3Dv4 for a while now with my setup and recently bought the full version so I could wrangle some better button assignments. All this week though I've had an issue when in the air (and only in the air) that the zoom keeps resetting every couple of minutes.
closed down connecting applications in turn to try isolate
turned on logging in FSUIPC
Removed FSUIPC from sim
When I removed FSUIPC from the sim I no longer had any issues. I also use Little NavMap and FightConnect for P3D, both of these were turned off during step 1 and the issue was stil reproducing.
I turned on logging for FSUIPC https://pastebin.com/E18VkkvT and thought I'd found something. Each time it happened I would pause the sim so I could read in the log where it happened:
249328 KEYDOWN: VK=80, Waiting=0, Repeat=N, Shifts=0
249328 .. Key not programmed -- passed on to FS
249328 *** EVENT: Cntrl= 65561 (0x00010019), Param= 0 (0x00000000) PAUSE_TOGGLE
I thought A HA! VK=80 would always appear just before my PAUSE_TOGGLE event... but then I later realised that VK=80 is the P key...
So I removed FSUIPC from the modules directory and no longer had the zoom reset issue.
Of interest, this only happens whilst in Flight. I can sit and taxii on the ground for ages and have no issues.
I am using the LDR Grumman Mallard from SimOutHouse and am unsure if it is affecting other craft but I guess I will have to load one of the default aircraft and see if it happens there too. However it is worth noting that this has only started happening after I registered.
Config file attached and log file extract in pastebin https://pastebin.com/E18VkkvT
Hope you can help.
