More typos than usual

I’ll be the first to admit that, as I slam out posts, I’m a lazy proofreader.  You may have noticed more typos than usual, though, and I actually have an excuse:  I have a Microsoft wireless keyboard, and for some reason it’s not forwarding to my computer full information about the keys I’m striking.  About every tenth keystroke vanishes.  I catch most of the mistakes but, since I am a bad proofreader of my own work (not, funnily enough, of other’s), a lot of mistakes are getting through.  I apologize.

By the way, have any of you experienced this problem with the MS wireless keyboard and, if so, do you know how to fix it?  I’ve check my batteries, which are fine.  I’ve also gone online for troubleshooting information, but have only found articles about complete failures to communicate between keyboard and computer, not partial failures.
