My webcam has been working in VISTA successfully for over a year. I reformatted my hard drive and reinstalled drivers from logitech website. Message said satisfactory installation but no prompt to connect camera. When I click PROGRAMS/LOGITECH MESSENGER it takes me to to "notifications" box then nothing at all (reverts back to desktop). I have tried three times uninstalling and reinstalling but without success. Logitech now tell me it won't work with Vista (even though it has been). Help please.
