How to Prevent SLD* Files from Updating When Nothing Is Changed

To experts,

I have been experiencing the solidworks behaving against the way I want.

When I open a SLDDRW file, sometimes I see * symbol at the window title, indicating there was a change made since the last save.

It makes sense if I really made a change. But sometimes it happens even when no change was made to the DRW itself or dependent SLDPRT file.

I am wondering if there is any setting in SolidWorks to prevent this behavior.

Thank you
