I requested experts of Firefox to help me out. Till date there is no reply from experts. My browsing experience is not at all happy.

That is this setting that you activate by pressing the mouse scroll wheel.

• Tools > Options > Advanced > General: Browsing: "Use autoscrolling"

Press F10 or tap the Alt key to bring up the "Menu Bar" temporarily.

Many many thanks for the reply. It has solved the problem of circle appearing below pointer/curser during internet browsing.

However this circle appears in microsoft office-excel work sheet and outlook express while working.

How to remove it from there?? Kindly help.

I'm not using those programs. It is either a feature of those programs or a feature of the mouse driver.

You can check out the mouse wheel setting in Control Panel > Mouse

THank you for help. As suggested, mouse wheel settings checked in control panel. Circle is not feature of mouse wheel or any of the programmes like microsoft office-excel work sheet and outlook express.

Looks like circle is a small software of Firefox which gets installed alongwith Firefox. Thereafter, it penetrates other programmes on the computer just like a virus.

I tried "add remove programme" on control pael but this software doesnot appear in the list of programmes. So difficult to remove it from Excel and outlook express.

Pl. help.

Are you aware that most scroll wheel mouse's (meese, mice?) now-a-days have a middle-click function on the scroll wheel? The default Mouse Properties in WinXP have absolutely no mention of that feature, at all. On the Button tab, the picture doesn't even show a scroll wheel, and the Wheel tab has only a setting for "notch" roll prefs. Nevertheless, pushing down on the mouse wheel serves as the "middle-click" function with the Microsoft P/S2 Port Mouse (Intelli-point) drivers that come with WinXP.

Sounds like that mouse may be wearing out, possibly a weak spring for the "click" action on the scroll wheel is allowing a middle-click when you don't intend to do a middle-click. My advise is to substitute a different mouse and see if that problem disappears.

You are absolutely right. I tried another mouse and the problem was solved.

I was not aware of middle click function of the mouse. The problem was with the middle click of wheel of mouse.

Many many thanks for the helping me out from this problem.

You're welcome.

I have been using the same model mouse for 11 years now (ball-type, infrared wireless, dual-scroll wheel, P/S2 house-brand A4D), got 9 of them on clearance when WinXP came out because this model didn't have drivers for WinXP and they were like 3 bucks a piece. I just loved this mouse so much that I bought everyone on the clearance table. The silly thing is that I don't even need any special drivers for this model mouse, the one special feature it has doesn't even work in Firefox anyways. I have seen the problem you have at least twice with the "middle-button".
Over the years bits and pieces have quit working, and I would have to grab a new one from my stash. Well a couple of years ago I ran out of new ones, so now I am down to doing surgery to keep a working mouse. Fortunately, I saved all the ones that gave me problems and it seemed that almost every one I "retired" had a different problem. So I figure that I have enough pieces to mix and match to keep one or another alive for the next few years at least.

That's amazing long usage. Before 11 years, we had not even heard of wireless mouse / seen one and you are using it since then. Hats off to you. You must be using computers a lot and must be having a lot of experience in troubleshooting as can be seen from your solutions and answers. You also seem to have mastered the repair technique to avoid costly replacements. Would love to read more of your solutions if time permits. Pl. send link if possible.

Once again many many thanks for the right solution.
