system options - spontaneous changes

Hi all,

I regularly need to go to SysOps and re-check the box "dynamic highlight" under Display/Selection.  By regularly, I mean approximately 1-2 times per week.

I am using 2015 SP5, but I am fairly certain this has happened to me in previous versions.  And, I would claim without evidence or 100% certainty that this has happened to other settings in my Sys Options.

Are there hotkeys that I could be pressing by mistake that turn these off?

Any ideas why this might be happening?

Anyone else see this?

Thanks,

-Nate
