Steps to reproduce / test case:

On the help screen, when using the Ctrl+F search box, the found text is highlighted with an almost unreadable shade of gray. This continues if using the Enter or arrow buttons that are placed at the search box's right.
To be able to see the highlight properly, one has to, for example, use the mouse scroll over the help text or click the scrollbar, which makes the highlight color to turn into a readable blue, with text on white (like the default color for selection on the text editor). From then on, using the arrow buttons keeps using the blue highlight, until the user clicks again in the search textbox, which causes the color to turn again into this almost-invisible gray.

This is a regression from Creator 1.2.
