Yes I am using Chrome on a Windows machine. English Wikipedia is where I have had the problem. Sometimes when I hit save the text simply does not save and everything is as it was before I tried to make a change. I am always logged in when I edit. Typically occurs when I have cut and pasted stuff into the edit box. There are no error messages just no changes. Have not yet tested other browsers or computers. I was hoping someone else has had this problem already and thus it had been figure out :-)
