Can't ESC out of Copying

Something I’ve noticed for awhile but haven’t commented on is that I’ve lost the ability to ESC out of a drag copy operation. For example, if I’m dragging from one tab to another and decide to cancel, I used to be able to hit ESC and it would cancel out of the copy. Now hitting ESC does nothing.

I have confirmed that the behavior works as expected in the default finder. Is there something I’m missing or is this simply something that needs to be addressed in TF?

I’m running TotalFiner 1.6.17 on Yosemite 10.10.2

Thanks,
