Cheers @ryanburnsred, we are continuing to investigate the issue .. if you could let me know which computer hardware you are running (is it custom built box?) or computer model? thanks a lot. By the way, I assume that if you disable the Tobii Serivces (Start -> Run -> services.msc -> Tobii Service) then you can sleep the PC?
It’s not a very elegant solution, but you could make a little batch file ‘Net Stop “Tobii Service” ‘ which you could execute before sleep as a workaround until we figure a proper fix.
