ok update, uninstalled office 2000 pro (or premium as it calls itself) using install CD, re-booted, then reinstalled. Flawlessly! Still get same problem - program (word, excel, powerpoint) starts opens wizard and is stable, any attempt to open new document and program closes after about a second. I'm soooo baffled. Got rescue disks for my PC - mebbe just reformat and reinstall everything is the way to go? Seems a bit drastic to me? Anyone got OfficeXP? and a VLK (joke! - well ish!) Dodger
