Most Frustrating!

It's has been a most frustrating day and a half ... a 6-month old 'stable' laptop running on Vista suddenly developed a conflict/windows issue with its USB port drivers and refused to let any USB plug & play devices work including my wireless stick and all memory sticks. A computer restore was enabled this morning ... I'm still installing and restoring the laptop now some 8 hours later! So A Light In The Darkness may not have its usual flavour tonight ...
