How to turn off Visual Studio 2010's new collapsible section mouse over highlighter?

Question

So it seems like the new VS highlights whole sections of code when the mouse is over the collapsible line on the far left of the IDE. I don't know what this feature is called but I couldn't see any option in the Options to turn this off.

Is this possible? If so, how?

Answer 1

Go to Tools -> Options -> Environment -> Fonts and Colors.

Select "Collapsible Region" under the "Display Items" section.

Then set the "Item Background" to "Automatic" or the appropriate background color for your editor.
