Write access?,Failed to save document?

Hi Guys

SW 2006 When I call up a Drawing I get

C:/prog/landscape/sw/data/a4-land scape is not available for write access do you want to open

document(s) Read only?

I Want to edit the sheet and save it actually!

Next Edit sheet  format

Edit sheet

File save sheet format

Ends up with "Failed to save document" ?

Last but not least..

Tools /options

Grid OFF

Units 4 place

etc.

etc.

Won't stick?

The next time I open the same assm or part or slddrw. the defaults are back.?

(My Tool bars reconfigured stick though)

Is this an admin right thing?

Thanks

Tony
