cursor jumping on laptops

I notice that when typing on a laptop, the cursor occasionally jumps to another line up the screen.  I notice it happens when I am typing in google docs.

I thought it was just me, but I see that others have this problem too.

Apparently this is a problem with Windows.

So one solutions is to not use Windows.

Another solution is to use an external keyboard.

And the author's solution was to use a program called touchfreeze.

I think I'll try it.

Wait, here's another solution: disable the touchpad.

It's Fn F10 on a SamSung laptop.  What is it on a Dell laptop?

Here's the Dell information.  Unfortunately none of the hotkeys worked on this Inspiron 1440.

And can't find it in control panel.

Go to Dell.com, look for Inspiron 1440 and download Alps touchpad driver

hey there it is in the control panel now

and I see there's an option to disable touchpad / pointing stick when external USB mouse is present.

OK, try that and see if the problem re-occurs.

meteor explodes over Russia

(Reuters) - A meteor streaked across the sky and exploded over central Russia on Friday, sending fireballs crashing to earth which shattered windows and damaged buildings, injuring more than 500 people.

People heading to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt a shockwave, according to a Reuters correspondent in the industrial city 950 miles east of Moscow.

The fireball, travelling at a speed of 19 miles per second according to Russia's space agency Roscosmos, had blazed across the horizon, leaving a long white trail in its wake which could be seen as far as 125 miles away.

Car alarms went off, windows broke and mobile phone networks were interrupted. The Interior Ministry said the meteor explosion had caused a sonic boom.

"There have never been any cases of meteorites breaking up at such a low level over Russia before," said Yuri Burenko, head of the Chelyabinsk branch of the Emergencies Ministry.

Russia's Emergencies Ministry said 514 people had sought medical help, mainly for light injuries caused by flying glass, and that 112 of them were kept in hospital.
