It’s not really a rule, the problem is my English, is not very good eheheh.
I do that just to clean all the old FSUIPC stuff, I saw it in the pdf manual and I thought it solved the problem.
The first times I updated FSUIPC.dll it was like you recommend, just replace the FSUIPC.dll file, but then and all the times I have the problem and I try to clean all files related to FSUIPC.
The times I had this problem I click with the mouse in the “Autothrottle Arm Switch (A/T Arm)” and the switch turns “On” and then in the next second it always turns automatically “Off”.
I just cant understand what causes this problem… I only know that this problem always appear to me when I updated the FSUIPC.dll , Is possible to be a coincidence I don’t know… :roll:
