The keys all work, but the j and the space bar, in particular, are sort of dull and, well, a bit non springy. I was hoping it might work itself out if I just continued to use it - oh, now I see the u is affected too...most of the others are ok. I tried cleaning with q-tips, dipped in water and sqeezed out....probably going to have to be a new one - will that mean going back to Dell or can I jjust get one from the high street? I know nothing about these things...
