Okay, I think this has only been going on in the last few days.

 

I'll be logged in to the board (of course) and reading several posts at once in different tabs. I'll be trying to reply to one of them as the rest of the pictures on that thread are loading or whatever...suddenly the page will go blank and my reply wil be lost before I can copy it and the bottom of the page will suddenly say "You must login/register to post to  this forum." My other tabs will not have logged out on me. But if I want to post to that thread, now I have to go back and re-click on the thread I was trying to post into. Reloading doesn't affect the situation.

 

What could be causing this? Am I going to have to stop using multiple tabs?

Gosh I've no idea...it might be the tabbed browsing

wow, de ja vu. I thought for sure I answered this. Is this still happening?

I've been trying to keep my multi-tab usage to a minimum, but it doesn't seem to be happening today.

Perhaps it is related to the simultaneous post issue?

I don't know, our site is acting a bit glitchy. Time for an update.

i know that if i am posting then go away for 10mins and come back i have to log in again, even though i tick the 'remember me' box, this has also only happened for the last few days as it used to remember me.
