Ok, So at my company we run office 2003. When my boss opens powerpoints from the network and saves them to the network. When he tries to re-open the ppt he gets te emessage M:\(name of powerpoint) is being modified by glennk. Do you want to open a read-only copy? The crazy thing is my bosses username is glennk. He is the one that just closed the document.... Any help much appreciated.
