Holding Left Mouse Button Invokes Windows Task Switcher

Question

I've noticed an odd behavior since recent Photoshop updates. Many times while I am holding down the left mouse button and painting with the brush tool or moving an adjustment slider back and forth, Windows brings up the task switcher (same as holding down Alt+Tab) (see screen shot). The screen shot shows this happening while painting with the brush tool. Never used to do this before. Seems to happen during relatively long hold and move sequences. Windows 10 Pro 64 bit, Photoshop version 21.2.0. Not sure why or how to make it stop. Thoughts?

I've discovered the source of my issue. I have a Logitech wireless mouse that has a "Gesture Button". It's a stupid little non-button that just happens to resided just under my right thumb. I've never bothered to try and find a use for this feature, and really never paid any attention to it. Lo and behold, the default assignment for this feature is "Switch Screen" which is what was invoking the task switcher. I have now set the assignment of this feature to "None" and my problem is solved. Moderators, please feel free to remove this post from the forum, since it was never a Photoshop issue to begin with.
