I looked there but as I said before everything seemed normal I don't
understand how it happen. Also I checked permission tab gave users full
control but nothing changed

look at the security permissions on the folder, it may be set to read only
for one pc but full access for the other

I use my files on a network share. there is only 2 pc. I shared some of
folder on the other pc and mapped that pc as network drive. I opened excel
files, add some information on it but when I saved it a dialog box opened. (
this file is read only files you have to save it with another name) so I
couldn't save my files on the other computer. I controlled the boxesbut none
of them ticked. It seems everything is normal. Have you get any idea about
this problem?
