Documents folder has lost options

I have noticed in my livrary the documents folder has lost it`s "group by" and "sort by" options sort by is shaded out - is there anyway to get these back

Thanks Mick

I should have thought of that i hope this is ok this what come up as you can see the options are missing

I have done that and they are still missing/shaded out

I fixed this myself - i created a new documents folder and removed the old one -

GOOD ON YOU!!!! It has been the same since DOS. More often than not it is easier to do an end run rather than charging up the middle fighting the OS all the way.
