blocking start-up warning dialog "some executions were not released..."

Hi all,

Using the teststand API I'm occasionally getting the dialog: "some executions were not released the last time the teststand engine was destroyed" when I start up my application. 

For the most part I'm cleaning up everything correctly, and it doesn't come up very often, but sometimes it does. So I have two questions:

• Is there a reason to actually care? What is the corrective action to take? 
• Is there a way to block this dialog from ever appearing again, either by taking those corrective actions or by handling some sort of UI event?

Thanks
