Does anyone know of a util or hack that forces this. When I close something, I want it to close, not minimize.
That's correct. Hopefully HTC will create another workaround once 6.5.1 and 6.5.3 eventually make it to devices (officially)Another thumbs up for the showcase task manager.
I think I read somewhere that the reason the x doesn't close it is because the new 6.5 interface moved the X to the lower right of the screen, but the default task manager still looks for it in the upper right corner?
