If you have TSM installed and open a profession window the ATT list will spawn on the side of the screen from the top of the screen to the bottom. I'm assuming because it doesn't have a window to anchor to. If you set it so your profession window opens to the default Blizzard frame it anchors correctly and is sized correctly.

Anyway to add a check to see if it's the TSM window and anchor to that?

Not a huge issue, just a small QOL item.

This is a known thing and how TSM works. It completely rewrited the profession UIand not sure if there is a way to anchor it. I believe Crieve knows about it and not sure if it is an easy or possible.

You can switch to the default WoW UI and then make use of our mini list there. Since the frame is no longer locked to the edge of the screen with TSM enabled, closing this ticket.
