Hi pcmeissner,
I’m assuming you’re referring to EE 1.6.5…
The jQuery extension is something that any add-on has to be modified to take into account.
Once we release an update of Tag with this compatibility, it will make that jQuery file obsolete, per sey. I would keep it there anyways, and make sure that no other software is using/sharing it.
Until then, you’ll need it still 
We plan to release updates to all of our software for this
