Pointer problems w/last update

Question

I don't know if this is a mouse problem or an update problem, but I'll give it a try.  It actually started with the update before this latest one, and the problems persist whether I'm on a webpage or in Mail.
If I click on a message in Mail slightly too hard, it automatically opens in its own window.  Closing that window oftentimes opens another unrelated message further up the list in its own window.  When I delete a message from the list, it most often takes the message immediately preceding it with it to the Trash folder.  It's also very hard to click and drag a message to another folder, like it doesn't want to capture it.
On a webpage, highlighting text is a challenge.  It either doesn't want to do the whole word (just a few letters), or it will highlight the whole paragraph.  Moving the highlighted text around the page takes several attempts.  There's not much control.
Clicking on something in the Bookmarks bar or any drop-down menu feature is a hit-and-miss event.  It usually takes several tries.
I know it may sound like operator lack of precise control, but I've not had problems like these before.  I'm using a wireless Logitech mouse with fresh batteries.  Everything worked perfectly before these last 2 updates.  Is it time to get a new mouse, or is anyone else experiencing these problems as an update issue?

Answer 1

What you describe sounds a lot like what I used to experience with wired mouses on my G4. The microswitch under the primary click-button would weaken and start to flutter (best way I can describe it) - it would autonomously multi-click on its own when I pressed and held it, and often add clicks when I released it. I'm a heavy mouse user, use it a lot more than the keyboard - my guess is I was just wearing them out. Typically such a mouse would last me less than two years before needing replacement, sometimes less than one year.
I would try using a different/new mouse and see if the problem disappears. If it does, it was certainly the mouse itself at fault.
