| 3 | # Implementation of the bgerror procedure. It posts a dialog box with |
---|
| 4 | # the error message and gives the user a chance to see a more detailed |
---|
| 5 | # stack trace, and possible do something more interesting with that |
---|
| 6 | # trace (like save it to a log). This is adapted from work done by |
---|
| 7 | # Donal K. Fellows. |
