Thanks for bringing this up here as well.
We are aware of that and there are some posts in TheHunter forum too: http://forum.thehunter.com/viewtopic.php?f=102&t=67778&p=720767&hilit=eyex#p720767
We’re investigating, as we haven’t been able to reproduce it yet.
Could you let me know what version of EyeX you are using? You will be able to see it in the About tab, in Tobii EyeX settings.
