dell inspiron 530 windows7 dell mouse part # xn966 laser about 4 1/2 "
by
2 1/2 " seems simple plain to me

while doing a left click, the right finger also does a right click maybe
because left click and right click are close together
the right click brings up that long column of "print, select all, encoding,
etc." and is a nusiance to whatever you are trying to do with the left click

If you have had a similar problem, how did you resolve it? If you actually
traced it to the type or size of mouse, which one did you get to replace?

Thank you
