The NI emblem is just a window with a pic. Lookout creates the windows first. After a while, it destroys the windows. So, it is supposed to be closed.
One possible reason is that when opening the process Windows is overloaded and can't refresh the display in time. Maybe your process is too big. It's just my guess.
Another reason is that the "close" message is not handled correctly by Lookout. But without reproducing it, I can say if this is a bug.
If you launch Lookout without any process, will it work properly every time? If yes, next time you can launch Lookout first(run lookout.exe), and then open a certain process.
