Actually I thought it would be OD, but it isn't. Even after I quit OD the maximized window's titlelbar is cut of from top as the image shows. It's just that there isn's visible shadow on top, it's just cut off.
And yes, selling but not supporting a program is my main issue with Stardock at the moment.
I could give you at least 3 currently supported programs that they should kill instead of ObjectDock: Groupy, DeskScapes and tiles.
Btw SD still sells OD even though MS only sells W10. Who even uses anything else anymore as MS doesn't support W7 anymore.
