NPCs unable to open doors

[EtPerMun]

OK, so I have now installed quite a number of xLovers mods and their prerequisites (MBP, x117 etc.), and they are all working fine. I have a completely different problem, though - NPCs can't open doors unless I'm around. This minor bug manages to screw up nearly every single NPC's schedule, as they can't leave their old location. After a little testing, these are the facts I've gathered:

a) NPCs cannot (or won't) open doors.

If we're in the same area (I think the terminus is "cell"), they suddenly can (and will).

c) This applies to all doors, whether locked or unlocked and whether the NPC has a key to that door or not.

d) a) happens everywhere in the game world, regardless of distance (or at least in both the IC and Bruma).

e) In a new game, a) does not happen, at least not immediately.

f) The mods I installed right before a) started occurring are numerous xLover ones as well as MBP, x117, BOSS, BU, Pluggy, Skeletons and OblivionXP (i.e. prerequisites for the xLover ones).

It should be noted that BOSS always puts the two MBP ENGs at the wrong position for some reason :-\

Any ideas on this?

Also, completely unrelated:

Is there any way to change the font size in the reply window? And why does the search function activate while I'm typing?
