VKB-SIM

I took delivery of an Modern Combat Pro Twist v1.99A a couple of months ago. Updated the firmware to v1.99B, calibrated and everything worked flawlessly. It is a real joy to fly. A REAL JOY STICK! But recently I had to reinstall windows , new graphics card, etc. Interestingly some of the buttons did not seem to work neither in the joy.cpl of windows or the VKB Device Config utility (v0.91.37). I checked all of the connections, the black box was showing a blue and green LED like it always does. I was about to take the thing apart but really could not understand why buttons 9-13 (4 way switch on the left side of the stick), slider 2(the pinky trigger) and the twist axis all seemed dead at the same time. They are all on the lower half of the stick so I thought maybe there is a smaller pcb somewhere in the stick that controls all the stuff on the lower halfwhich failed. But before doing this, I tried recalibration.

Amazingly, everything works fine now.

Almost like the stick had a small seizure and forgot about its lower half. Has this been observed before?

Without providing screenshots of the Global-External, Profile-Axes, Profile-Buttons, Povs, Test-External Devices tabs, it is very difficult to determine the reason for this behavior. If this happens again, please attach these screenshots.
