Kepler

In the actor parameter editor dialog, the background color is blue for values if the string mode is true. If the parameter has choices and string mode is true, the background should also be blue, but on Linux it is white. An example is the Array Peak Search actor's scale parameter. The color is white on Linux in Kepler and Vergil, but blue on Mac in Kepler and Vergil. I also confirmed this behavior has changed since Kepler 2.0.
