Thanks for the suggestions
Raze.
It's not the shield that's the problem, it's the inventory slot itself. The slot remains grayed out even when I don't have a shield equipped.
However - Good news!
I once again removed all of my equipment and placed in my inventory. I had tried this before but I must have missed a ring or something. Once I was completely naked <img src="/ubbthreads/images/graemlins/eek.gif" alt="" /> my shield slot was no longer grayed out and I could equip my shield again.
I'm using v1.44, so possibly that bug was fixed in 1.45. I don't want to patch though, because I like all the money I get from arrows. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
