Some touchpads are sensitive to side pressure.

So if you rest the heal of your hand on the laptop surface near the touchpad, it might determine
there is some touchpad contact that you don't intend.  

Also, some touchpad software can have special functions on the edges of the touchpad area.
 Those can usually be disabled going into the touchpad configuration/properties on the operating

I have also seen problems of inability to maintain pointer position, and these tend to be
sporadic.  One thing to do with OpenOffice installed is disable the quick-start functionality
and see if that helps.  I don't think OO is the problem but it might be a case of too many
applications hooked into the input stream.  Also, on Windows laptops, you might check to see
what applications are in your startup list and see what ones you can disable without any consequence.
 These will usually be identified as from non-Microsoft sources.  Custom screen savers and
such, also screen capture utilities might be disturbing things.

I've had the zooming problem before, too, but only with LyX, not OO. I've 
noticed it happens when I drag my finger along the touchpad in just the 
right direction at just the right place. But, I've had a very hard time 
trying to duplicate it, and for whatever reason, it hasn't happened to me in 
a long time.

I have a Sony Vaio with Win7. I've had other touchpad issues. I've found a 
few ways of dealing with them.

1. Before I do any typing, I place the mouse cursor in a benign part of the 
screen so that, if I brush the touchpad nothing will happen. Usually, I put 
it in a blank part of the menu.

2. You can disable the touchpad tapping feature by going into the Control 
Panel, Hardware and Settings, Mouse, Tapping. With tapping disabled, you'll 
have to actually click the touchpad buttons instead of just tapping the pad. 
It's a bit of a pain, but the trade off is that you don't get the unwanted 

While this may help with inadvertent tapping issues, I'm not sure will will 
help with the zooming, but I could be wrong. However, as others have said, I 
don't think it's an OO issue, but rather a system issue.

you don't say if you have researched the issue. I took a quick look
online and one possibility among several is a driver conflict. another
is a need for an updated driver (to be downloaded from the input
manufacturer's website).

were it me, I'd first update the drivers and see; then I'd go to
device manager and stop a driver (e.g. wifi) and see what happens and
repeat systematically to see if anything helps.

but guess this is off-topic for this list; sure hope you find a
solution. I wouldn't live with the situation.

here is the first link I found on the matter

(interestingly one person found it was a charger issue!)

you might also search for the problem referencing your specific laptop
model. probably others with the same problem and a fix.
