When a Gift Batch is setup with a Default Solicitor, users receive a search window populated with the Solicitors name when tabbing to the next row.
This issue occurs when the Constituent selected as the default is not marked as a Solicitor on the Bio 1 tab of their record. Open the Constituent Record to the Bio 1 tab. On the bottom right corner, mark "Is a Solicitor." The Constituent search window will no longer pop up in Batch.
