P: Zooms out while trying to subtract from current selection

Thanks for letting me know, David - sorry you weren't able to recreate this. Must be different circumstances between us. 
Jane - Thank you for confirming that it does the same thing with a mouse! I guess it's not my tablet..Certainly hope this is fixed soon.
I forgot to include my OS - I am on Mac Catalina 10.15.1, and have the latest photoshop CC 2020 update installed. 

Hi

I am using an iMac and a mouse and can confirm that it is as Lisa describes. Make a selection, then Cmd+Opt+Click a layer thumbnail and PS subtracts from the selection as it should, but also zooms which it shouldn't. This new annoying behavior was introduced with PS 2020.

I am on High Sierra with 21.0.1

This help file says what PS should do with Cmd+Opt+Click:

Howdy Lisa,

This being a bug is news to me.  And I'm the shortcut guy!  =8^O

I just tried it with a mouse and it works fine.  Heck, I TRIED to break it and it just worked.  It's gotta your Wacom.  I'd bet dollars-to-donuts that your tablet is also sending additional, spurious commands to the app.  It would hardly be the first time...

I wish I had happier news for you,
Sorry,
David

Hi David,

Yes using a wacom tablet. I exclusively work with a pen and tablet, and don't have a mouse I can test with (at least not a non-wacom mouse).

However, some other folks on the adobe community page alerted me that this was a bug, so I assume it does the same with a mouse. 

Thanks!

Howdy Lisa,

Using a tablet, right?  Which brand?  Have you tried without the tablet?

Just a hunch...  

Thanks,
David
