Slightly erratic mouse

My desktop PC uses Win7(32) and it has a wireless Optical mouse.
Recently I changed the Mouse batteries and it continues to work ( red light underneath ). However, I'm experiencing rather odd effects when left-clicking to select items. ( eg in Wordprocessing and Video Editing which are far apart in Processor-demand ).
It does work, L&R buttons and in Control Panel I've selected the "Slowest" speed for clicking, but it continues to be rather jerky when selecting...like it selects and then doesn't. I have a steady hand, so I don't think it's User Faulty, but that's what it behaves like.
Change the mouse, I hear you cry!
Today I tried a wired-mouse....but maybe I've forgotten something - but from a cold-boot with USB wired-Optical connected (and the usb- radio dongle thingy removed), I expected the PC to recognise the wired mouse...but no.
[ The mouse is in a bag marked "OK Win7/32" - so I must have used it some while ago, before wrapping it up in favour of the Wireless one.]
Plugging-in the radio dongle even without reboot and the wireless mouse springs into action - with the same erratic fault - but at least it works.... so I'm able to shut-down Win without those pesky messages.

Any thoughts?- - - -
1) on fixing the wireless mouse?
and
2) as to why I can't use a known working USB wired mouse?
Wired mouse does flash red when plugged-in if the USB radio dongle
is present . . . . so I guess the power is getting through . . . .
Wireless mouse has two extra buttons on the Left, can't discover what they do, but they are never used. It's a Technica Model.
 
Well, I thank you for the effort, fourtunately I fixed (?) it with another wired mouse.... this worked correctly and Programs now behave a lot better. The Optical mouse I took apart, but frankly with sm components there is little to see - even with a x10 Lupe. I cleaned off some surface junk/flux and re-assembled it (twice!).... it seems the optical alignment is rather fussy....
However, this proves that the "Device is working normally" in Control Panel / Mouse . . . is far from perfect. Indeed it might be said to be a lie wrapped in an enigma. . .

So it seems that in future I need to have a spare wireless mouse glued to the side of the computer; so I can break open the pack and check it against the "Everyday" device. [i.e. as quick as saying "Mouse!" ].
