Unusual Metaserver Error

When executing a Cubase macro on Metagrid Pro 1.6.6, running Windows Metaserver 5.1.4, the following 2 lines are displayed in the Metaserver console:

Info
Invalid action comes from multitask Task type: Unlock Application
Invalid action comes from multitask Task type: Lock Application

The macros are executed successfully, but the 2 lines are always logged.

Does anyone else see this?
