happened during Windows 10 spring upgrade. WD b70 is running and sending correct data to wunderground and CWOP, but the main display screen refuses to appear on my laptop. as a side note, both previous windows April updates wiped ALL WD setup, configuration and data info as if i had just installed WD for the first time! it has been a bad month…
maybe it is running hidden in the system tray
where do you have WD installed to and running from?
WD is in the WDisplay folder on drive C
it has always run hidden in the system tray. hovering over the WD icon shows a mini version of the main screen as always. clicking the icon once has always expanded the main screen to standard size until the Spring upgrade.
It might be opening off screen
.zip and email me your settings files,and I will have a look
