I wonder if anyone could offer some clues here...
When I am typing on Facebook or in internet forums, my cursor often jumps to some random place. Quite often I can be typing away and it will have jumped to somewhere else in the text or even out of the text so that when I hit backspace, it triggers the 'back' function of my browser. I can't count the amount of times I've lost whole posts to this phenomena.
It only happens with my laptop and I've never experienced this on my desk top system or any other system I've owned.... (there it goes again, while I was typing this!)
I use Google Chrome, since I had to stop using Firefox due to innumerable issues, rendering it pretty much unusable. I can't remember if it did this in Firefox or not.
Just wondered if anyone else has encountered this and if they know how to fix it? I don't know if it's a Windows 7 bug or a browser fault.
