There seems to be something up with the global inbox feature since the planned outage. I was alerted to a response of some sort (red blob) but upon visiting the inbox there's nothing there:
This is in Chrome 13 and Firefox 5 on Windows 7 Ultimate x64 even after restarting both browsers.
The comment added below red-blob alerted me and it's in the inbox but nothing else is there, i.e. the original alert described above.
