Looking at the bottom of the Sequence Editor window, it looks like the model is called "TestStandModel.seq", which lends credence to the idea that this is a custom model (we do not provide a built-in model with that name). Also, it looks like the name of the dialog box is being cut off--I bet if you resize it with your mouse, you'll see a more complete name for the box. It looks like some kind of execution monitor window.
This is almost certainly a process model customization, and could likely be disabled by editing the process model to skip or remove the steps which display the dialog. If you'd like to look through the process model and try to find the relevant code, you can just double-click the text at the bottom that says "TestStandModel.seq" to open the process model.
Also, if you obtained the model from another developer at your company, it might be worth talking to that person to get more insight on why the dialog exists or how you might disable it for your testing.
