An annoying quest book icon keep popping up.

[xxclare38xx]

Hi, i have used Carbonite for the last year and recently formatted my pc, after i put them all back on add-ons i mean, i noticed this very annoying quest icon(like a book) keeps popping up in the left corner, under my portrait i did have this before but for the life of me i cant remember how to turn it off as its very annoying. Obviously it is something that pops up after i accept certain type of quest.

Please help!
