Mouse/pointer behaviour

Hi!

I would like to ask for some explanation to this annoying mouse/pointer behaviour I have been facing during times on several machines.

I do not believe it's caused by a virus or other malware, but rather by some kind of  operational activation/interference of some "legal" program/service running on the machine at the same time.

So, the problem behaviour occurs quite often suddenly during typing text on e.g. Word-document, Notepad, or an open IE-window text-box, like just now happened also on this EE Ask body-box ... The text-typing pointer jumps from the on-going typing position to somewhere else inside the previously typed text on the text-box or document, and the typing is continued there at a wrong place!  After a while noticing this happening, you have to clean out or mark the text there and transfer the pointer and the marked text to the right typing position continuing the typing there!  

This is very annoying!  Especially for users who are not so used to the computer typing, which I have some as my support clients.

Is there any explanation for this behaviour? What is activating this jump? Do it have something to do with the mouse-pointer position on the screen, text-box or document during the typing? Note, the mouse-pointer is another one, than the actual text-typing pointer, which may do the annoying jump ...

This behaviour has been seen on several Windows-, Word- and IE-versions, now on Win7, Word 2007/2010 and IE9.

In the Control Panel, click on Mouse options...

Next open the "Pointer Options" tab and insure all settings match your desired preferences!

Within the Mouse Properties (as above) uncheck "Enhance pointer precision", and click apply, that will stop the mouse from acting crazy

If they are on a laptop they're probably bumping the touchpad with their thumb[s] while typing, which is like clicking the left mouse button... it moves the blinking text cursor or focus to where the mouse pointer is located.

Hi!

OK, thank so much for all the replies.

I think jcimarron's reply is the most "comprehensive", leading to an earlier thread on this same subject, with some 85 posts around this problem covering maybe all aspects for this.

I have been several times testing the different mouse settings, but so far not seen a cure for the problem.

For a few weeks ago I once again downloaded fresh copies of the latest original touchpad/mouse drivers, deleted the devices from Device Manager, re-booted and re-installed the devices with the fresh drivers.  And, did see some enhancement on the touchpad and external mouse behaviour, but not still a final cure for the jump problem.

Now I have to begin to test these different hints one by one during several days/weeks, and let's see what comes up.  The testing with either the touchpad or external USB-mouse disconnected seems interesting.


Best regards,

Pete V.
