When you create a new weapon, on the "Art and Sound" page you need two Pipboy icons. One icon for the inventory image and one for the message icon.

The message icon "Edit" button is not properly linked to the correct function.

It should bring up a selection dialog for a .dds file. Instead it brings up a selection dialog for a .nif file for "Mod 2" on the "Mod Info" tab.

No! The "Edit" button for "Mod 2" does not bring up the message icon selection dialog.

What is worse is that the Message Icon Edit button WILL change the entry for Mod 2 on the Mod Info tab.

At present the only solution is to paste a "MICO" record into the saved .esp file using something like TESSnip or FNVEdit and edit the record outside of the GECK.

The GECK will read the MICO record it's just impossible to edit or create a new MICO record inside the GECK for a weapon.
