Hi @sarahhosni, thanks for your report. As you may know the old Tobii EyeX has now been deprecated
and replaced with the Tobii Core SDK whose homepage is @ http://developer.tobii.com/tobii-core-sdk/
Whilst there has been a considerable amount of improvement over the older SDK, the syntax is similar.
I wonder if you could kindly replicate this issue using the new Core SDK on your system and let us know
if the problem persists.
I would say the included sample application “Interaction_VirtualWindows_101” available for download @
https://github.com/Tobii/CoreSDK would be an appropriate comparison. Many thanks.
