This has happened a few times to us - A spreadsheet saved on a common drive (not shared or protected) suddenly and for no apparent reason saves with the suffix [Group] whereupon no one can use the Autofilters or add anything to any of the cells. I have never heard of this issue in the 10 years I have been using Excel and no one here knows either.
Last time this happened, we had to copy all the cells to a new file, wreaking havoc on the others shortcut keys.
I dont know if this is related but I also have been having a strangish problem, when I open a new Excel window, it says personal.xls is locked for editing by ''. I have been hitting cancel and resuming my work.
