I suddenly can't open office documents (ppt, word or excel docs) in entourage when people send them to me as attachments. i think there was a software update recently, and maybe it was this that caused it. But, it is driving me crazy. I can open the attachments inside mac mail fine. In Entourage, says they may not be a ppt, or word, etc. doc, or that they may be "in-use." HELP!
