Thanks for the response. The identical error happened again last night, but I was not able to capture the message, although it looked identical. And oddly in both instances it seems to happen after working in the browser for maybe a couple of hours - with virtually No idle time per se. And also last night and the night before, this 'timeout' error happened "You session has expired". Can't remember if this happened before or after the error message. What session? Again, not really any idle time per se ... other than looking at help pages for various things in another browser window. And again noting this is Google Chrome. I would seem the browser version is a bit unstable. I hope this get resolved soon, because whereas I hope to upgrade 'this' system to Win 10 Enterprise over the weekend, at work (Southern California Edison), we are on Win 7 ... so the browser will be the only option for some time to come. And as I noted in another post, you can suddenly get into a mode with 'Save' does nothing at all (does not save). Once this happens, you have to reload - and of course lose whatever you are working on. Fortunately, I frequently hit Ctrl+S 🙂
