Replication Monitor won't show (Error details or messages of the select session:)

Hi,

since I had a bad error in replication, my replication monitor won't show the tab "Error details or messages of the select session". 

I am not able to activate or to show this "tab", to get all information about my error.

I added two screeshots, one with the 3 tab, and the other, were the information about my error are missing. Any idea, how i can my default view back?

Replication Monitor OK:

My Replication Monitor with missing tab:

I had to know, which ID is causing a primary key violation. It would be nice, if someone could help me. Instead of Replication Monitor, I would use t-sql.

Thanks a lot

Regards,

Andreas
