PHOTOSHOP CS6 - Zoom Flies In and Out Randomly on MaCOS 10.11

First the specs: I am on a MacBook Pro running OS X El Capitan, 10.11.1.

When I am in Photoshop (CS6) and have an image open, my zoom feature just zooms in and out at random, and I'm not talking about just a small zoom here and there. It will zoom in to the tiniest possible number then fly up to the maximum level.

Most frustrating is when I am doing detailed work, I am zoomed at 1600 and I need my window to remain at that level without the zoom suddenly flying around up and down and ruining the detailed work I am doing. It's maddening.

Does anyone know why my zoom has its own brain and zooms in and out very quickly when it has a mind to do so?

One more thing just came to mind. As I am working, when I move left to the tools to change to another tool, like the eraser or paintbrush, then it's a sure thing my zoom is going to go psycho.

You are hitting something (key, mouse wheel, etc.) that causes the zoom.
First you need to figure out what you are doing to cause the zoom.

I appreciate your prompt response, but I assure you I am hitting nothing to cause the zoom. I, too, would give someone the same advice if he or she came to me with the same problem, but it simply isn't the case.

With my MacBook Pro, I am not using any type of mouse. I haven't used a mouse since the 1990s.

Going along with your line of thinking, however, when this got to be a problem, I checked and watched everything I did to see if I was causing this issue. There is nothing there.

If anything else comes to your mind, I would be so grateful for another suggestion. I'm wondering if it is a setting somewhere, but I don't know where.

Again, thank you for your assistance.

Some event has to be given to photoshop to cause the zoom.
That could be a pinch on the trackpad, touching the zoom control on a wacom tablet, scroll wheel on a mouse, etc.

Somewhere, there is an event being given to Photoshop that says to change the zoom.
And most events are going to come from user input.

There is no setting that would cause zoom level changes without user input.

My next guesses would be someone trying to control your machine remotely, or malicious software on your system.

Also, you really should install the latest MacOS updates -- Apple is fixing a LOT of bugs in each 10.11 update (current is 10.11.3).

Mr. Cox: Again, I thank you for your assistance.

Actually, I did find some settings that I changed and it seems to have done the trick. Being on a Mac, I don't have to deal with malicious software very often. In fact, I've been using Macs since the 90s and have never had any type of third-party trouble maker.

And, using a MacBook Pro, I'm dealing with a trackpad instead of a mouse. I honestly don't think I could get anything done on a computer with a mouse, even if it was an Apple product.

You make an excellent point, however, about keeping my Mac updated. I do tend to be quite undisciplined when it comes to updating. Thank you for pointing that out. At your prompting, I updated my computer earlier today. I still have some more to do, but I need to get some work done before I do those.

God bless.

What settings were causing it?  (so other users with the same problem can solve it on their systems)
