Any Dragon users out there?  My Dragon setup works pretty well, except that when I type in Word or the search box on Google, I cannot type the letter C.  When Dragon is not loaded, I can type all letters just fine, but when Dragon is either minimized to my system tray or is on my taskbar, I cannot type the letter C.  Anyone ever have this happen?  If so, did you solve the problem, and if you did, how did you do it?
