Not sure if it's replicable, but...
I had my incarnate powers window open
I slotted an incarnate power (banished pantheon partial radial improved ally)
Without closing the incarnate powers window, I opened an auction house window.
I attempted to place inspirations in the AH (restoration): it would appear in the AH window, but not transfer from the inspiration tray. When I dragged it over again, it would duplicate in the AH window, but again not disappear from the inspiration tray.
When I attempted to post the items (price, 25 inf) they would not post until after the incarnate powers window was closed. When the incarnate powers window was closed, the inspiration disappeared from the inspiration tray as expected.
