Beta 1 worked fine for me but just upgraded to 9.5 Beta 2 and the settings window just shows the DF logo for 30 seconds then disappears. Based on searched from previous thread I did this:
- sfc /scannow
- dism /online /cleanup-image /restorehealth
- disabled active protection on AVG antivirus
none of the above seems to make a difference. Thanks for any help.

So I went back to 9.4.3 and that still works fine.

log file attached, thanks for your help

Also - my trial ends tomorrow but I'm still trying to see if DF works for me - is it at all possible to extend my trial period?

good news, tried beta 3, DF settings now loads normally.

But that 2 second startup delay of the move window to next monitor button is still there, unfortunately.
