On the history page of OH browser, the pages visited are listed (apart from ones viewed in incognito). Lots of these are from Gmail. One of which is listed as "(something I don't recognise) logged on from another computer ". When clicked on, it says that email has been deleted. Unfortunately, the description in the history list then changed to the normal email address after I'd clicked on it, so I can't go back to check the unrecognised bit out.
What kind of thing would be giving an alert on Gmail? I thought it would only be the Gmail account itself, if logged on from another computer. But in that case, why didn't it have the usual name? Any ideas?
