Could not resize graveyard to put triggers on stack

[kingofcheezwiz]

I cast Treasure Cruise using delve. I expanded the graveyard so I could select the 7 cards I wanted to exile. Once 7 were selected, I was prompted to place my triggers on the stack, but the images for the triggers were stuck under my graveyard window which I could no longer rescale because the game wanted me to place my triggers on the stack before moving forward. I was forced to close the window and concede the game, because I couldn't click on anything else. Clearly a bug that needs to be fixed.
