Run the Dell diagnostics - which include a keyboard diagnostic.  F12 at powerup.

I am having the same problem, did you get it fixed.  I already did F8 process, Didn'

Did you find out what the solution to this? The SAME thing is happening to me. They have replaced the hard drive, keyboard and palm rest and the problem still exists. The service tech who came out said that he had never heard of this problem before.

I am having a similar problem but it is as if the ctrl key is being held down intermittently.  I get shortcut dialog boxes popping up--for instance when I type a "s" the save as box comes up.  I am on my third studio1737 and they all do it.  I reported this problem 6 days after I got my computer and Dell says they won't give me my money back and it is a problem I don't think I can live with the problem.

Does nothing to help!!!!!

I am having the exact same problem, but with a studio 1537.  I have to use an external keyboard because the problem is so annoying.  Paragraphs get deleted, windows pop up...it's driving me crazy.  Dell told me to reinstall Windows, but I doubt that will help.  I wish one of the Dell moderators would come to this thread and give us some insight, because we sure aren't getting answers elsewhere.  I am never buying a Dell again, I have had more problems with this computer since I bought it!

I was having somewhat of this issue whilst typing. I figured out it's because
the meat of your hands rest in the corners of the touch pad. Only way I get
around it is type carefully when I use the touch pad, or setup the pad to turn
off when a USB or other type of mouse i detected. Haven't had problems
since.

I too am having the same problem in original post.  Have only had the laptop for a week!  Was on the phone w/ tech support last night for almost 2 hours.  They reformatted my machine, but the problem still exists.  Doesn't seem to matter if I'm in email, chat or a document.  Does anyone know if reseating the keyboard will resolve this problem?  Or even replacing the keyboard?

I have had the keyboard replaced twice and it did not fix the problem--I am beginning to think that it has something to do with the touchpad.  You would think Dell would figure that out.  I have had 2 replacement computers with the same problem.  I did go into the touchpad settings and changed the touchcheck to maximum and it seems to have helped but you would think Dell would figure this out.

Okay, so I took the advice of someone else on another thread, and got an external mouse...the Dell/Logitech one actually.  I plugged it in and changed the mouse settings to disable the touchpad when an external USB mouse is plugged in, and the problems seems to have been fixed!  So I'd give that a try guys!  And thanks for the info, goingtobuyamac.  Annndd yes, you'd think Dell would figure this out instead of replacing parts and telling us to reinstall Windows!
