Tested under OS X 10.2.5...

Create a new project and drag a listbox and an editfield to the default window.

Bind (shift-cmd) the two controls together, select any of the bind rules and click OK.

RB will eventually crash with a kernel protection error. (try saving the project or quitting rb, for instance.)

This also happens when you try to bind a bevel button to enable when a listbox has a selection. In my experience, the RB crash/quit is almost immediate; as if when RB finishes setting up the binding and control returns to the event loop.

Is there a feedback id for this yet?

I don't see anything relevant on a search on "binding"; shall I go ahead and create one?

For the interested parties here, this is the crash log:

We haven't seen the type of looting of government offices as is
