So my Unity crashed, I did a reboot of my machine (OS X), and now I can't seem to view the Sprite Collection editor window (version 2.3). I select a collection, click "Open Editor" and nothing happens at all. No errors or messages in the console, nothing. I thought maybe the window is just popping up off screen somehow, but I've reset my displays, gathered all windows, relaunched everything and I can't figure it out. I've re-installed 2DTK, rebuilt indexes, etc.
Please help!
EDIT: I'm seeing this error in my console:
Failed to destroy editor windows: #1
tk2dSpriteCollectionEditorPopup
UnityEditor.WindowLayout:LoadWindowLayout(String, Boolean)
