Minecraft 14w10b, Minecraft 14w11b, Minecraft 14w17a
MacOSX, survival, on map created in earlier snapshot. Same result in creative, on map generated in this snapshot.
When standing at a normal distance of a chest/furnace etc, with an item frame on it, the chest won't open when clicking on the chest, but the item in the frame rotates instead. Also when trying to open chest on the lid above item frame.
It's also not possible to place another chest on top of the chest with the item frame.
On a double chest, you can move to the side and access the chest normally, where there is no item frame. Also from the side.
Back up a little and it opens like it normally does.
I searched for duplicate issues will now continue to search, since I'm usually never first at reporting.
