I have more than one source code file in my project.
I did a search in one of them for "LOCAL". The cursor / window scroll position would appear to move to the first occurance of this word, but it would not highlight it in the editor. Pressing F3 and the next one is found but it still does not highlight the found word.
Now change to another source file and then back again to the original source file. The word is now highlighted and pressing F3 to find the next will now correctly highlight each word found.
It seems the bug is pressing Ctrl+F (or choosing the command from the menu) will not highlight the found words until you change to another source code window.
Fixed in next updt.
