Bonjour,
I have uninstalled Display Fusion this morning and since then, I can't drag maximized windows unless Aero Snap is activated. I used to be able to drag maximized windows before installation of DF, though, I can't remember if it was a registry tweak or a windows 10 option (I believe it's the latter).

Even if I set the registry with a disable Aero Snap, it doesen't work.

HKEY_CURRENT_USER\Control Panel\Desktop
DragFromMaximize DWORD
0 = Disable
1 = Enable

Do you have any idea what could be the problème?

Thanks for your help
