I am running the latest version of AE CC 2015 and am still having "sticky" layers and keyframes. When I select a layer and make and adjustment, the pointer doesn't release or let go. It drags layers around won't let go of keyframes. Sometimes I select a layer and it accidentally grabs the layer above it and moves it below the layer I am trying to select. When I try to move a keyframe left or right, it won't let go of the keyframe and I have to switch to the mouse to get it to let go. The tablet doesn't do this in AE CC 2014. I updated to the latest Wacom driver. I have replaced the nib in the end of the pen and am going to try a different Wacom Tablet. Thanks!

Well, AE CC 2015 22.214.171.124 has crashed on me 3 times today while trying to animate. This time I was using trim paths on a shape layer with a stroke. As I slid the offset parameter I got the spinning beach ball and had to force quit after waiting for some time. I guess it is back to CC 2014 again until 13.6.2. I really want to use 2015 but there are so many bugs.
