Perhaps you can catch at the top of the C++ code and then convert to Objective-C compatible exceptions by re-throwing from an Objective C++ module.

This isn't possible. As a general rule of thumb, if you didn't compile it yourself, you probably can't throw through it.
Try catching all throws at as low a level as possible without going back into AppKit, like this:
Our c++ code - throw occurs here.
Our c++ code
Our c++ code - try catching here
App Kit / Foundation
App Kit / Foundation
App Kit / Foundation
App Kit / Foundation
Our handler
App Kit / Foundation
App Kit / Foundation
Root of the stack
And then post some sort of notification so the run-loop can know what's going on.

Please could someone tell me if this is not possible (c++ exceptions can't be thrown through app kit / foundation methods, for eg). Alternatively, could someone confirm if it's definitely possible, and we must have something set up wrong.
