Thought it was just me - DEL definitely does not work.

I rolled back to 11 but to no avail. It's has something to do with the Lenses and Synthrack. I created a new project and just recorded a bar or so of audio and was able to use the delete key to delete the clip. I opened the synthrack but didn't open any instrument and just recorded a bit of audio and was able to use the delete key. I inserted a piano and recorded  a bit of midi and was able to use the delete key. In a new project I created last night the delete key would not work no matter what workaround I tried. I did notice when I opened the synthrack the lense flashed. I don't use lenses so it's set to none.. Also I like to keep my synthrack docked to the right of the track view and this is where it always is when opening a new project but now it seems to dock at the top of my left display which has my console view my right display has my track view. So for whatever reason in this new project the delete key works.
 

Doesn't work here either even after changing key bindings..

The delete key wasn't working for me either. My Synth rack was docked at the top. When I changed it to the bottom, the delete key works now. Bug.
 
Update: My Show/Hide Track Inspector (I) stopped working also. Once I moved the synth rack to the bottom, it worked again.

My delete key also doesn't work? If I move the Synth Rack to the bottom it works, I've also tried other projects and most of them can delete, but the new projects are a bit inconsistent? This and recent "Crashes" Win10, makes it a bit disappointing?
