I'm having the same issues. :'(
Sounds to me like something keeps refreshing that page in the background. Try downloading some sort of "tab reload" plugin/add-on and set the page to be reloaded every 25 seconds
Also be sure to not minimize your browser in the background, since that can cause issues for some people
To add on to what everyone else is saying, if you don't want to download a url refresh plugin, I use refreshthis.com. You don't have to download it, and it works really good for me. :3Cheers everyone for helping. I'll try the web adress and use it for a few days and if it works I'll let you know. ^-^
