Same thing here.I noticed it, starting yesterday, but thought that it was my web browser. Every time that I go back to a page that I've visited I have to refresh it, or it shows only what was there during my last visit. Now I've confirmed it on 3 separate systems.
This is really getting frustrating... every page I go to I have to refresh. With a recent PM too, it keeps popping up every time I go to the homepage that I have a new message but its just the same message. Any idea's from GTA Tech support.
