I think there's a bug in the toolbar event handler.

Glad you're enjoying it :) What you're seeing is almost always due to an exception being raised in the Python callback (which has nowhere good to go in a windows app - need to think about what to do there). The first thing to try is replacing the body of your callback with just 'pass' or 'return'. Now, if you can click the thing that calls it w/o getting an error, you've verified that theres some prob with the Python code. If so, 'the debugger is your friend', as Jim always tells me :) Put a import pdb pdb.set_trace() ...at the top of the callback method code and go from there. Given the one-liner in your example, the only thing I can think of is if MessageBox hasn't been defined as a name (maybe you need to use the fully-qualified name or import that name explicitly?)
