In Source Insight 4.0 running on Windows 10, I came across a highlight problem. After any word being highlighted, the word is covered with a yellow rectangle and can not be seen anymore (as shown in picture-1).

Though the word can be seen by selecting it once more (as shown in picture-2), it's unbearable to see the yellow rectangle once the word is highlighted.

Could anyone help to resolve this problem?
