I'm using Windows 7 x64 with Office 2007.When users save file in excel to "My Documents" which is redirected to a network DFS location it sometimes take up to 2 minnutes to save the file.We can take the same file and save it 6 or 7 times in a row wihtout any problem but sometimes it takes forever. We never have this problem on open, only on save.Any ideas ?
