Latestarter, just keep on pestering the doctor(s) to figure it out. Eventually, they will send you to a doctor that will.
I'm still getting use to the new o-ring dampeners. I LIKE them. I barely have to touch the key and the letter appears. They're pretty quiet too, although you can hear that I'm typing. I've had this keyboard a little over 4 years, and it still works perfect, so I've gotten my money's worth. I don't look at my keyboard to type. It sure looks pretty though, even from across the room. I especially love that I could program my own lighting on the keys I use for gaming. You can program quite a few macros into it too. For example, instead of hitting Control, Alt, Delete, I can program it, so I hit one key, and it executes the sequence.
