Hi

Whenever I enter an interior (except dungeons it seems) all manner of things start flying around, books, carrots, sweetrolls.

It is as if my character is haunted!

In one case three people got killed by flying apples!!

It is also highly annoying as there is always some bottle or kettle that seems to repeatedly slam frenetically into the wall or floor with a thumping sound that makes a lot of noise.

Does anybody know what may cause this?

I suspect some sort detection system placed by a mod

did you disable the Vsync? flying objects is a common problem encountered with havok items when the fps gets too high.

If you have V-Sync disabled, turn it on. Likewise, if your FPS is going above 60, cap it at 60 or lower. The latter is if you have a monitor that has a different refresh rate from 60 Hz or if you just don't like V-Sync. Physics issues are generally caused by an FPS greater than 60.
