What steps will reproduce the problem?
1. move item from bag to bank or visa versa

What is the expected output? What do you see instead?

No changes registered in button frames. buttons for items put into bank bags remain visible.

If a disenchantable / millable, etc.. item is removed / added to inventory professionbars should make / remove button for item.
Right now, if buttonframes are separate, addon doesn't update at all (unless item is being looted, mailed or a profbars_button is pressed.)

And while attached to tradeskill frame only when tradeframe is opened or profbars_buttons are pressed. No changes are being registered while the frame remains open unless the addon executes a professionbars:push_item(); (by pressing a profbars_button)

What version of the product are you using?

r42

Please provide any additional information below.

Maybe add an on BAG_UPDATE event?

Yeah, I'm aware of BAG_UPDATE, sadly I wasn't aware of it when I was first coding ProfessionBars (it was my first real addon back then) and simply haven't bothered to change yet.

I've added a fix that's packaging right now, get the beta.
