Agentry - must wait at least 2 seconds after entering value to save

I have a transaction screen that contains one data entry field.

Oddly enough, the transaction doesn't save the information if you click Finish immediately after entering the value.  You have to wait at least 2 seconds after typing in the value in field before I can click Finish, or else the data doesn't get saved.  Waiting 2+ seconds to click Finish after typing in the value saves the data fine.  I'm using SMP server 3.0.10.5, SMP SDK 3.0.11.1, WPF Agentry client 70.11.0.5, and Agentry editor plugin 70.6.2.23.

Has anyone seen this behavior before?

Thanks
