Mirror Help, please

[Spinell]

Still getting used to a few of the modifiers in Blender 2.6, and the one that's giving me a bit of a hard time is the mirror modifier.

Why? Well, you see the mesh looks fine in edit mode, with all the vertices merged with each other, all nice and stiched together. But whe I go into object mode, the mirror part is not "glued" to the other half. I just don't know what's goin on or how to fix this, since it looks fine in edit mode.

Here is my modofier stack:

Armature (it's a rigged mesh)

Smooth (can't be the problem here, can it?)

Mirror (Y axis; options: merge, clipping and vertex groups enabled; merge limit: 1mm)

Solidify

 

A little help fixing the problem please? ;)

you most probably will want to have the mirror modifier on top of the stack, so that it gets calculated first. otherwise you get undesirable results like what you currently see.

I am an idiot sometimes...

Thanks for the help, Gaia. That fixed it.
