Dia. Symbol Displays as

This started yesterday.

Is this a toggle somewhere or perhaps something our terrific IT department caused?

I'm thinking it is something I did.

Any input is appreciated.

2008 SP4.0 and this happen on the part level and also on Drawings which where previously displaying correctly.

Thank you.
