Has anyone seen the TestStand 3.5 User Interface disappear during testing?

[plf]

The user interface disappeared while a test sequence was executing. The Windows Task Manager showed LabVIEW (8.2) and TestStand running but nothing was present on the taskbar for TestStand and the window could not be found. This has only happened once but I am being pressed to explain this hence the question.

plf,

By user interface you mean an operator interface?
If this is the case, what operator interface are you using?
Have you seen this several times?
What kind of sequence were you executing?

Regards.
