Objects appear red when highlighted problem

[skyeg3206316]

I opened revit this morning and now when I hover my mouse over an object it turns red instead of blue like it used to be. Also my section is showing up red. Does anyone know what happened? Thanks in advance.

Try adjusting the highlight color.

Purple Revit icon>Options>Graphics.

see attached image.

I think this problem may be caused by a recent windows 7 Update: Platform Update for Windows 7 x64-Edition (KB2670838)
