Photoshop tools always open sub menu.

[tklow]

I've been having this problem for about a month.  I have PhotoShop CC 2018 on Windows 10 and it is updated to the latest edition. The problem showed up at the same time as those incredibly annoying video tooltips (which I have already disabled).

Now, when I left click an item on the tools palette, it always acts as though I have clicked and held to open the sub menu (right-clicking does the same thing). I cannot use any tool without clicking twice: once to open the sub menu, and the second time to select my option.  Has anyone encountered this?  It is not happening with any other Adobe program and it's a major time waster.

Restoring my settings to default did NOT help.

Try resetting all Preferences:

As I said above, I did restore my preferences to default and it did not help. I did this both by the method indicated above, and I also removed my settings file manually to force PhotoShop to create a new one.  Neither had any effect on my issue.

Reset All Tools by right clicking on one as shown here.

I'm afraid that did not work either.

Though, it did somehow introduce an error:

     "Could not complete the Exit command because of a program error."

That's new.

Ok, next: Follow the instructions to uninstall Photoshop and run the cleaner tool:

Use the Creative Cloud Cleaner Tool to solve installation problems and then reinstall.

Sigh.  Nope.  I did it twice, just for fun.  Same issue.

Ok, something about CC 2018 not getting along with your OS/Hardware. You do have the option to install an earlier version of Photoshop. Keep CC 2018 and when a bugfix is released, try it again.

From your CC Desktop:

Then pick an older version. CC 2017 and if that is not good, CC 2014 is a good choice.

I should have replied a while ago, but ... amazingly, removing all traces of the new version and reinstalling the previous version, did not fix it.  I cannot fathom why.  I gave up.  Hating PhotoShop so much now.

Have you considered using a different mouse (it may be lingering when you lift your finger) or adjusting mouse controls in your computer OS?

[tklow]

Well, no, I hadn't considered that but it would be odd for it not to affect everythign on my computer.  Also, it happens 100% of the time, not once in a while.

But as it happens, my mouse died ten days ago and I installed a new one.

As a designer, I only use top end gaming mice because I have a RSI and need very high resolution and plenty of customizeable buttons, so I don't think that could be the case.

Just a follow up.  It's been close to a year. tried all of the above fixes including rolling back versions, reinstalling, etc.  Same issue. Not the only issue I have with the current version of Creative Cloud (way more problems with Illustrator) but still, annoying enough I avoid PhotoShop as much as possible these days.  I decided to post again because Adobe has a habit of answering questions with suggestions that do not work, then marking their own answers as correct. Not cool. Your fixes did not work.

I had this problem too long now. I chose to ignore it. But now I found the culprit. My magic mouse (version1). I used an app called JITouch to enhance the magic mouse's functionality (I used the middle mouse click function). I disabled it one day and the sub menu is not showing now. I re-enabled it. and the problem is gone now. I think this third party app utility is the one to blame (I guess for my case). I hope this helps.

I just had this issue and solved it by changing the "double click" setting from the windows mouse settings. it was close to "fastest" . when I bring the slider to middle the problem was gone. 
Maybe it helps somebody.
