In Noah version 4.8 HIMSA introduced a feature that allows for the merging of duplicate patient records. When duplicate patients are merged, one of the records is deleted.

In versions of Noah previous to 4.12.1, the deletion event can cause modules that may be open to crash.

Noah does not allow you to merge patients with modules open on the machine where you are working, the following message will be displayed:

However, if you merge duplicate patients on the server and modules are open on a workstation, you may experience the module crash on the workstation.

This problem is fixed in Noah version 4.12.1. To realize the fix, Noah 4.12.1 must be installed on all Noah machines; the Noah server and the workstations.
