What's your problem....?
I understand relatively well these 3 systems, but there are always little problems that often have nothing to do with the system - like on Facebook - where these 'wizzkids' are always changing something - then taking it off again, leaving you searching in vain for what you want. It would be nice if they could just make sure whatever it is works,then LEAVE IT ALONE.....!!
Right now, I have one of these problems, with BLOGGER, the editor which allows you to write/edit/delete on your own Blogsites. Whether this is another one of those things between Windows and other systems I don't know, but I can open the editor on Linux (which I'm using right now) or on Google Chromebook, just not on Windows!
Isn't it great fun when you have to go onto a site you haven't used in months/years, and it continues to refuse your password...? What the devil was my password back in 1999 anyhow....?
