If I use the ‘X’ at the top right corner of the window to close the Quick Actions menu, it’s fine. Use the Cancel button, touch input to CM disappears - the mouse cursor still moves to the touch point but CM does not register any input touch button presses.
Yes, you are right. It was the chance I hit, not the x.
Unrelated but annoying bug in CC. If I open a file to look at something and then close the window without doing anything really it pops up a bugsplat window. I just ignore it. The hang in CM is harder to ignore.
Maybe I need a quick action that doesn’t do anything if I really wanted to cancel, like opened by mistake or whatever.
