Looks like a call stack bug. I'll probably need a saved game to figure out what's causing it. The best is a saved game from a while before the bug with step-by-step instructions on how to get to the broken dungeon, but a saved game in the dungeon with the menu gone will also work.
You can use the form at
http://spikycaterpillar.com/savegame-upload.html to upload saves; once you've done so, post or PM me so I know that they're there and whose bug report they go with. (The page also has instructions on where to find the saved games)
What's happening is that somewhere a piece of code (possibly much earlier) didn't return properly and the game just kept going - so once you reach the dungeon it thinks you're in the middle of casting a spell and disables the UI.
Question: is the game where the bug hits one that was loaded from a demo save? (As that helps narrow down where I need to look.)
