Help !!

for some reson two of my macros's attached to two pics in my worksheet have
'dropped out' and the right click has been somehow disabled so I can't edit
the pics so that I can reattach them.
The worksheet is full of various bits of VB code (most of which has been
donated from here) so I don't even know where to start looking in the VB
editor for the potential problem.

Anybody any ideas to help, or what to look for in the code??

many thanks
