This is my first time back to the forum in several days so I have not read some of the information provided.
I can tell you that on my Windows 10 PC, not a tablet, turning on Tablet mode is not an option. When I click in the Windows 10 system tray on the Notifications icon, it pops up 12 boxes for various Windows Notification Settings but the only one which is greyed out, preventing selection, is the one labeled "Tablet Mode".
Once I was pointed toward the LAUNCH app, I started changing various settings but with no success even after multiple reboots.
Yet today, I rebooted due to a system being very slow and suddenly the extra-large application icons are back??????
I don't know what I did but now, after rebooting a few times, when I click on Start10, the large Launch buttons briefly show up again at the top of the screen. Once I click on anything, they disappear again so they take up desktop only briefly, when needed.
I would love to offer the solution that worked but I have no idea how I got them back and am left to wonder when they will disappear again.
I will greatly appreciate it when Stardock repairs this application's stability and functionality.
