GoldenRivet: Unfortunately exactly the same thing happened to me just minutes before. Suddenly without any particular reason I'd know about my TDC dials started their own lives, not reacting to my clicks. I've got latest OLC GUI with GWX 2.0 and that's my first patrol with OLC. That was going to be the first encounter. I played with the Range & AOB wheel as well as with TDC dials to get used to it and they worked very well. But when I made my approach to the prey... disaster.
The dials, when visible, were still reacting as locked - they changed as I moved the scope. All the rest worked (music, icons, views, key shortcuts and so on) but the TDC and WizWheel (Is-Was). I tried to bring it back by repeating what I'd done before, but nothing helped.
You're not alone, Herr Kaleun.
