Hello I have been using chaseplane for a while and I start my sim up and my middle mouse button was not working I am on the stable and I have tried reinstalling restarting and all that.

 

thanks

This may help. Had a similar if not exact issue recently and spent a lot of time working to overcome it.  I felt it started after a mid-December Windows 10 Auto Update.  This was an obscure find but it cured my ills. Hope it works in your situation.

In Windows go into Settings, Accounts, Sign-in options, and turn off the following option:
"Use my sign-in info to automatically finish setting up my device after an update or restart"
 

@fppilot that would not be it I am using windows 7 and It was working fine today and I tried to use it tonight and nope

Was worth a try?  My issue was clearly middle mouse, as in clicking or scrolling with my mouse wheel. What I mentioned has totally fixed it.  I was elusively chasing all sorts of other remedies, including too much diversionary focus on my Saitek devices. I kept seeing the presence of a Saitek mouse driver and I have never seen a Saitek mouse, much less used one.  I have other Saitek devices, but no mouse ever. Had to be happening from updates as again the issue is now gone!

 

Yea I tried that I can't even find the Accounts in the control panel I couldn't find it anywhere.
