Mouse schizophrenia

Something fairly quirky has come up with my iMac. When using the mouse (I am using a logitech mouse, not an apple mouse), it has become "schizophrenic," so to speak. I haven't changed any settings, but now sometimes when I click once, it behaves as if I clicked it several times. This is most inconvenient in my mailbox when I click to delete a piece of email, and it deletes 3 or 4 in rapid succession! Conversely, at other times, I have to click on something three or 4 times before it reacts at all.

I have actually swapped out mouses (mice?) and it does the same thing with any mouse I attach, so it seems to be in the computer, not the mouse. Anybody experience this, and anybody have any idea what's going on?

Thanks.

Here are some suggestions which may help:

If your pointer is jumpy when you use a trackpad, Magic Trackpad, or Magic Mouse - Apple Support

Another possibility is covered here.  Out of interest, do you have a Wacom table and pen in the vicinity.

Logitech's drivers have been notoriously flakey. They will generally have problems when a new update is released, then they will fix their drivers and issue an update. I gave up on them over a decade ago.

Try uninstalling the Logitech software and see how the mice perform. They will only be recognized as a basic mouse, but that will still give you enough information to decide if it is the drivers causing the issue.

It also can be a combination of other input device software as seventy one mentioned.

As a test, uninstall the Logitech mouse driver (I presume you have it installed). The mouse will continue to work as a simple, two button design.

Does the problem go away? If it does, then Logitech's drivers are at fault.

I've used Logitech's mice for a very long time. Their designs just fit my hand better. And I much prefer a simple two button mouse with a center scroll wheel/button. I always assign the scroll button as a double click. I really can't remember the last time I physically double clicked the mouse for anything since I automatically use the wheel button for that.

Anyway, a few years ago I had to replace my very worn out Logitech mouse. Got a new one and installed the latest drivers, which were supposedly for the version of OS X I was using. Every so often (at least once a day), the mouse would freeze. This could be in the middle of anything. Just moving the cursor across the screen, in the middle of a brush stroke in Photoshop, etc. There was no way out other than losing whatever I was in the process of and doing a forced restart.

I complained about it on Logitech's forums, only to find I was far from the only person with this problem. Since this was actually causing me to lose work, I had to find a different solution. That was SteerMouse. I haven't had an issue since. Still using my Logitech mouse, just not their drivers.
