Hi,

The email icon is not showing the number of emails anymore. It shows in the notification that I have received an email.
I've seen it show up once or twice, but i had 7 emails this mourning, and the icon shows nothing.
Any one got any ideas?

Please help.

I didn't find the right solution from the Internet.
