Here is a sympathetic highlighting bug which I can consistently reproduce:
1. Open NASB and NA27 Greek New Testament
2. Highlight an English word. The appropriate Greek words will be highlighted.
3. Click anywhere in the Greek text outside of the highlighted words. This makes the Greek sympathetic highlighting disappear, although the English stays.
4. Click anywhere in the English Bible. This makes the sympathetic highlighting go away (which is expected, which the focus changes). But it also makes the previous Greek sympathetic highlighting reappear, even though no English words are highlighted.
This is quite a consistent pattern.
