object problems!

[Gazbrad]

I had that problem at first on my iMac 24" but I realised I was running the wrong screen resolution. Changed it and I could get the items no problem. Chances are it's too high in the in game-settings, lower it a notch and it may help.

What I did with the shelves to get through to the hole at the back was to prise them apart with the metal bar which you pick up in the other dungeon room. Eventually I created a big enough space to get through. The hammer, as you said, doesn't break the wooden shelves, unless someone found out otherwise. Good luck, it's fun.
