Precision 5510 keyboard douuble characters

Hi folks,

I have a new Precision m5510 that works flawlessly save for the keyboard. It produces random double spaces on a single spacebar tap mid-sentence as well as  the odd double character.  The biggest issue is the spacebar creating double spaces mid-sentence and I am  now spending twice as long to write as needed! I am very frustrated. I have checked dreivers, tried  filter keys, bounce keys, etc and searched high and low in the internet for fixes. Is this a common problem with  the 5510s and is there some way to fix it? The keyboard otherwise works fine and I am not experience the squeeky  or sticky keys that other 5510 users have  mentioned elsewhere.

Best,

Erich
