The Rigol oscilloscope will show "Invalid input!" and beep incessantly when a new capture is started with pulseview. This happens when a previous run of PV has started a capture and PV was closed/crashed before the trigger. Steps to reproduce: 1. Start PulseView, connect to osmelloscope 2. Make sure trigger is set to single mode, not auto 3. Click "Run", and ensure no capture is triggered 4. Close PulseView 5. Start PulseView again 6. Click "Run" Additional info: libsigrok(-cxx)-0.5.2 pulseview-0.4.1
Please try with a current PV nightly.
