Not sure of prior version – but re-created with good connect on 5.1.62, then installed 6.11.2 and duplicated the blank screens – removed the 6.11.2 , installed the 5.1.62 again and I am working correctly. I will be sending logs from Windows and Linux machines
The latest version is what caused the problem. I completely removed/uninstalled the latest version and found a very old version 5.1.62_1 and it runs correctly – something with the new version is not right.
as previously stated, Ubuntu desktop with dongle on video card. Laptop with Windows 10 (upgraded from windows 7) both worked prior to latest version on my Windows 10 desktop (across town) connecting to both machines remotely – now works
Not sure what you need from me to help find a fix.
