I played around with swapping sim between the bb and another (nokia) phone to see if calls received. Then swapped them back. A bit later while still trying to navigate without the scroll button, it started working again !! Elsewhere on the web I've seen someone suggest removing the battery *and* the sim and putting them back as a fix. Seems unlikely. However on this model the scroll button is exactly opposite the sim location. Maybe fiddling with the sim pushes a loose contact or something - don't know. Thanks anyway - Terry.
