My Acer scanner no longer wants to scan transparencies or negatives. Scans images OK though. For transparencies & negatives the light in the lid comes on and a warming up message comes on, counting back '25...24...23..., but freezes and the '1 second' point. I think it may be clashing with other software as it was working under Windows XP earlier in the year. I believe I have the lastest driver (MiraScanv342s_BQA) Suggestions welcome. Thanks Andy
