The original analog discovery problem with WF 3.19.19 (windows 10, 64 bit)

[cephy]

I've been using WF 3.16.41 for a long time, but today I upgraded to the latest one 3.19.19.  The new WF recognized the original analog discovery fine, and then I setup the scope display (channel 1 only, 1V/div, 10us/div).  When I pressed RUN, it displayed the signal as expected, but a small message window was repeatedly appearing and then disappearing (alternating).  When I press RUN again to stop the scope, the small message window stopped appearing.  The message was about windows failure to connect to the device, which was weird because the scope worked.  I uninstalled 3.19.19, and reinstalled 3.16.41, the WF and analog discovery work perfectly again.

What was wrong with WF 3.19.19?

thanks.

Edit:  I forgot to mention, the RUN button did not change to STOP symbol like in WF 3.16.41, but the scope displayed the expected signal (perhaps a single shot).

Hi @cephy

Known:

-in Scope under time Options uncheck "Acquire Noise" otherwise it will give an error !
