Select Component Priority no longer shows face/edge preview

[Anonymous]

This has happened since I updated to 2012 Professional.  When I want to use the measure tool or add constrains in assembly mode, the face/edge preview does not show up in red under Select Component Priority.  I have to wait for the select other option to come up to see which face I am on.  If I click on the face or edge it will show up but not until I do.  I don't remember changing any settings that would cause this.  Is this happening to anyone else? I could have the select other option delay set to zero or I could change it to another selection priority but I don't remember having to do that before.

you can try to change the Color scheme to "Millennium" and check whether it works(see attached picture for details)

Thanks Mick.  Even though your suggestion didn't solve the problem it brought me to the colors tab under application options, where I found that somehow the "Enable Prehighlight" box was unchecked.  Didn't know that was even an option.

Thanks
