Has anyone ells had problems with resetting a domain service account not detecting it's being used in a windows scheduled task?

I’m currently testing PMP for implementation in production and have setup a very basic start:

• PMP is installed with one windows resource of the server with the scheduled task running under a service account
• Configured one Windows Domain resource with the service account
• Created one resource group with my windows resource in it
• And associated the service account resource to that enabling service account reset.

If I setup a service on that server with the service account then it detects and changes that but it doesn't detect that there is a windows scheduled task with the service account on that server.

Any have any ideas?
