Hello you all.
My Alfa Data trackball fell down yesterday. Nothing serious but one of the three rollers inside got out of its place so now it can be moved freely.
I've unscrewed the three screws at the bottom of the trackball but I can't still fully open it in order to put the roller back to its place. How can I open it? I've found no videos nor explanations. I've just been able to take the roller out the trackball.
Help!!!
