Remarks

This system tag changes to 1 every time the update signal is generated by selecting Notify Clients on the WindowMaker Special menu. $ApplicationChanged is reset to 0 when the application is updated. This tag can be used to generate a message that informs the operator that the NAD Repository application has changed.

You can also use the $ApplicationChanged system tag in a data change script to build a node update notification script. This script can launch your own dialog boxes or stop running processes. Then, you could use the ReloadWindowViewer() function to start the update process.
