Run VI Async cause TestStand "Hang"

[zou]

I need a status window and a stop button for my test sequence.  So I launch the status window async, and use the TestStand modal VI to make it model to the sequence editor.  It works as planed: the stop button stops status VI and the loop in the sequence; the sequence execution finished, report show up.  The only problem is that the sequence editor becomes hang/disabled after that.  I found a workaround using Windows API.

Anyone run into similar situation?  What's the right way to create a status window?

I can't switch to the simply or advanced LabVIEW UI to to run sequence.  It's not my call.

TestStand 2017, LabVIEW 2018, Windows 10 Pro.

The problem is the TestStand - End Modal Dialog.vi

Don't know why it fails to enable the Sequence Edit window when my status VI is launched async.

Since I have to use Windows API anyway, I'm going to use Make Window Always on Top.vi instead of the TestStand Modal VIs.
