User Interface Colour

Hi,

I've been battling trying to solve what is probably quite an easy fix for a while.

I don't know what key combination I've pressed but my SolidWorks UI colours have switched to an orange highlight scheme:

The rollback bar has also gone orange and my PDM Workgroup header bar is also a weird peach colour:

I can't see it in Won 10 settings as my highlight colour for the scheme is set to blue and I've also got the SolidWorks colour scheme set to blue highlight:

Any help would be great as its just an irritation for me!

Thanks,

Dave
