This is what it looks like if I were going to reinstall the driver:

I've had a similar problem with the R820T dongles ever since I got them.
It only happens with my R820T tuners and NOT with my E4000 versions.
Some of them are more susceptible to it than others.
But all of my R820T's will do that at one time or another.
I find that if I disconnect the antenna with a strong signal present, it happens every time.
Or, if the antenna connector is intermittent it also happens.
I have to STOP SDR# and unplug the dongle for a few seconds, then plug it back in to get it working again.
Sometimes I can turn the RF gain down and it prevents it from happening. (I never use AGC)
By the way, it's not just the recent release that does this, I've seen it all the way back to at least Version 1110
I've stayed with Version 1114 because with the releases after that, I don't like the way clicking on a frequency in the Frequency Manager plugin works.
With later versions, you have a hard time 'predicting' where the selected frequency will appear in the display.
