To stop all the madness of having to MANUALLY refresh the appstore, try this if you're using Firefox.
1. Download the 'Reload Every' add-on for Firefox.
2. Go to:
http://app-store.appspot.com/?url=ht...520Group-Title
3. Right-click, choose "Reload every" and set the interval. this will also auto-enable the add on for that page.
You can open this page in its own window, and OCCASIONALLY (!) Alt-Tab/Cmd-Tab to see the window...
Hope this helps the anxiety...it's helped me so far! :)
