Jeff,
Yes, it happens when I click the Continue button.
Selecting one of the sort choices, e.g., Taxonomically, solves the problem. Curiously, once the field is set I can find no way to make it blank again.
I wondering how it was cleared in the first place. The one thing I did that was different is that I bought and downloaded the 2009 AOU update and this is the first time I attempted the Checklist Entry method for that particular taxonomy.
Whatever the reason, having the software verify a proper sort method and warning the user would be more elegant that crashing the program.
