Entering Invitation Results causes ConcurrentModificationException and application exit

[Ken McLean]

Entering Invitation Results causes ConcurrentModificationException and application exit.

1. Enter one invitation result.
2. Enter another. After tabbing out of Lastname, a ConcurrentModificationException is thrown. Tabbing further crashes the app.
There was also a series of ZipUtils errors previous to this.

I tested this. I put in several invitations directly into results, ie not through bibno, and did not get an error. However, I do occasionally get thread errors. This has only started happening since the Thursday morning 8/09/09
