I have just installed Start11 beta.
It works just fine on my old Lenovo laptop running Win 10 Pro x64.
But when I install it on my Intel NUC NUC8i3BEH which is using my Samsung UHD TV as the display, if I try to adjust the font size the font jumps from 100% normal to about 20 times the size at any increase and will not return to 100%!!!
The only way back to 100% is to reinstall the program....
Shame really could be a nice feature if it worked as well on the TV as the laptop.
