I know my PC is old now around 8 years old to be exact, but it has started to move onto the next step of something before I have had the chance to click on the OK button.
Same goes for when I click back or forward on a web page, it often moves back 2 pages instead of the one, other transactions act like this too, and it can be very off putting.
And say I click on one of the single smilies, instead of creating one, it creates 2, I have to admit that this is intermittent, but is happening more and more now. I have just noticed however that it appears to create 2 if you click on a smilie which is next to a full stop for some reason or another
I have an optical wired USB mouse, and please don't laugh, but still use the dear old un-supported Windows 98 S.E.
This is one of the reasons that I will be getting a new PC in the fullness of time, but curious as to what may be causing the problem I refer to above.
