Using firmware 2.7.4 On occasion, i'm seeing the UI lock up to the point where I have to shut down and restart the kemper. Have seen this happen twice now with this firmware rev. I've also seen a variation of this where in performance mode, I cannot select a new rig using the type selector. I select the type but it never loads and eventually times out and reverts back to the original rig. Unlike the previous issue, the problem goes away when I unplug the USB cable so it seems as if an operation failed to complete. At first I thought it was rig manager but it just happened again without rig manager being involved. Seems like it's getting into a runaway CPU condition because when I turned the selector off it took about 10 seconds before it began the shutdown sequence. Anyone else seeing this?
