Conveniently, my laptop has built-in buttons for the functions Volume Up, Volume Down, Mute, and Oh Crap What's Wrong With My Laptop.
These buttons are apparently incompatible with my DDR pad. Each time I use the pad, the buttons stop functioning, and then I need to reboot the laptop for them to work again. As laptop problems go, it's really not so bad*, but it is very peculiar.
*On a day-to-day basis, I'm more inconvenienced by my laptop's unwillingness to access Google Calendar with Firefox. Whenever I try, it just reports "Firefox has detected that the server is redirecting the request for this address in a way that will never complete." I have not had this problem with any other computer or any other site. Consequently, I use Firefox for 95% of my Internet use, and then I leave a browser open with IE and Google Calendar.**
**My, what a long footnote that was!
