TestExecute interactive session fails when window is minimised

Hello,

I am running TestComplete 14.60 and TestExecute 14.72 on W10. 

My project suite is stored in an onprem ADO Git repo and feeds into an ADO build pipeline.

The tests execute and report normally on the 3 Test Agents I have configured in the test pool.

I currently manually open a Remote Desktop Connection (RDC) , logon to each machine and start the agent and TestExecute as Admin before launching the tests.

The tests will only run if the rdc windows are open (maximised or windowed).

They fail if I run the pipeline with the RDC windows minimised.

How can I avoid having this constraint.

Thanks,

James
