Look for a pair in column 6 and make some eliminations.
You can now fill all of the cells in box 5.

Thanks alot, that did solve the 5:th box for me. But mostly thanks for that link that both taught me about hidden pairs and eventually led me to Simple Sudoku, I've been wanting to be able to exclude candidates in another program i used. Now it's almost too simple.. =)
