Freeze on item pickup/transfer

There's a 1 to 5 seconds of frame drop/freeze every time I drag an item into any slot in my inventory. This issue is present with no quests accepted, all quests completed, max level profile, etc - I've even deleted the entire client, downgraded Live, and re-installed AKI R7 and got the same result. Anybody have any thoughts?

They're attached as files I'll update with paste

EDIT: Updated paste links to include text/uploaded file

I've seen it happen with a couple different mods so I'll narrow it down. Just figured it wouldn't hurt to see if anybody had seen this before I went to those lengths.

Thanks!
