Can one only have one specific Toolbox open in AR5 at a time?
Is this a bug or by design?
It would seem Toolbox’s are global, so no matter how many paintings are open only the Toolbox associated with the last painting to be opened is loaded.
Switch back to any of the other open paintings and that same last Toolbox is now there replacing the one that was originally saved with any given painting.
It would be better I think if possible that AR5 could remember the Toolbox state for any given painting and reload that when switching back and forth between paintings.
