Cannot delete track messages in User CP

[Rex_Mundi_Incarnit]

As the title suggests I cannot delete track messages in my user CP. These are related to the confirmed and unconfirmed message dialogs. As soon as I try to delete the whopping 207 receipts, I get logged out. Can this be fixed please?

EDIT: Nevermind really. When i select all but one, I can delete them. Sorry :)

EDIT: This is not really related but I cant delete my last attachment in my user CP. I can delete all of them except this one. Strange...
