I am getting the "We are unable to connect to the server. Your work may be lost....." alert. It's super annoying, so I disabled the "alert('<?php echo TEXT_KEEPALIVE_SERVER_UNREACHABLE_MESSAGE1;?>');" code to no ill effects.

I have noticed, though, that even when I click the "Yes, Keep Working" button, the header on the site continues to countdown, until it says "!!Expired Session" But It's not actually expired. Just the page's header says that. And the countdown isn't even consistent after clicking keep working, then navigate to another tab. It will hang out at like 181 2-3 seconds, 180 for even longer, sometimes flash the pages actual title, then continue counting down at normal speed once the tab is in focus. Once it says expired session, the next time the modal box pops up, it doesn't give the countdown, it says that the session expired and to login.
