My trackball has stopped clicking even though i haven't muted it? is very strange...

I'm not overly bothered just curious as to why?

your profile is still set to normal right?

it is set so that the trackball clicks yeh

do you mean the "rough" clicking sound made by rolling the trackball? If so, then you're probably going to have to clean out the trackball. You can learn how to do that in the 83xx Forum.
