Mr. called me the other day and mentioned that his Blackberry trackball wasn't working.
I told him how I clean the trackball on my mouse - I get a paper towel damp with glass cleaner and then roll it over the trackball. It works every time. I told him to try it.
I got this email back from him:
BTW, it worked!! I licked my BB (blackberry) trackball and it works again!
He said it tastes like cat food.
