There are few problems:

1. When profession windows (replaced by TSM4) is opened, ATT does not check its position and displays its own window with recipes list in place which is correct for original WoW's profession window. BTW, TSM4 window may be freely moved on the screen.

2. When mailbox is opened (in TSM4 version) and then profession window (original WoW), ATT may attaches recipes list to mailbox instead of profession window. You can also open profession window first and then mailbox - in this case ATT first display window next to profession windows, and after opening mailbox moves it next to the new window.

3. When I switch profession window from TSM4 version to WoW one and then back to TSM4, ATT starts attaching to correct window. However ATT does not check Z-order of TSM windows - e,g. when I click on profession windows or move it a bit, windows are displayed in following order (from the front): profession window, mailbox, ATT recipes list.
