When i try to use select and mask, instead of taking me to the screen in which i can set shift edge etc, it just takes me to a screen without the select and mask button and it does nothing

​@Jumbo3312  I am not sure where you are with this.  I had a notification which suggested you still hadn’t fixed it, so this might be redundant.  Just in case:

I turned off the sub panel, which I had floating mid-screen. I then used the reset, and the sub-panel returned, but aligned to the left side of the screen as below.

Let us know if you are still stuck.
