JetSetter Display Is Empty / Blank

[evolross]

On Meteor 1.8.1 and JetSetter 1.5.2 I have one particular app where JetSetter is showing a blank window with the cursor stuck far over to the right. I'm unable to type anything but can open and close the window. I just recently updated to Meteor 1.8.1 so I'm thinking this started happening then.

I know the Session has data because the app is working as expected.

I put a lot of stuff in the Session but have never seen this before. The weird things is I have other apps in this same configuration of Meteor and JetSetter that are working correctly.

Is there any debug option I can enable to see if there's an error happening somewhere?
