Door and chest activation issues during The Dwemer's Bone

http://www.uesp.net/wiki/Morrowind:The_Dwemer%27s_Bone

During The Dwemer's Bone quest, I found that I had great difficulty getting the door into Jeanne's bedroom activate/open and I found it impossible to open the chest where I was supposed to put the bone. Whenever I hit the activate button while looking at either, it would not activate them. Inexplicably, the door sometimes would activate, only if I was standing (not sneaking) and I seemed to be at a particular distance or angle, and it would always activate if I was running at it at the time I hit the activate button (though the quest would fail as I was always detected). The same issue would apply if I tried to close it again after opening it. Under no circumstances could I get the chest to open. I was able to get both of them to open instantly with "activate" in the console (therefore I could still complete the quest successfully), and after I put the bone in the chest and got the journal update I could open and close both the door and the chest as normal.

I couldn't find any reason why this should be happening in the CS, but my CS skills are quite bad. Any ideas? My plugins.txt is attached for your perusal if that helps.
