SAM always treats project file as modified

I'm using SAM 2016.3.14 on MacOS 10.11.6. If I open a .sam file and don't change anything, and then try to close it or open another project, SAM says the file has been modified and asks if I want to save my changes.

Hello,

Thank you for the feedback. We will try to improve this behavior of SAM in OS X. In the meantime, you should follow the prompts to save the file.

Best regards,
Paul.
