Search & Replace "in all HTML files" not working for more than 1 occurence in a file

What steps will reproduce the problem?
1. Enter "Search mode"
2. Select a string to be looked for, choose mode "Normal", Search "All HTML 
Files" (Direction "Down" but it should not matter)
3. Click Find
4. After you found an occurrence, click again

What is the expected output? What do you see instead?
If there is more than one occurence you should cicle through them, eventually 
jumping (opening) the next file.
That doesn't happen: if you look for a "common" item (like for example the word 
"io" in an italian text) you might be able to find a couple of many in the 
current file before the search function stops working. If it is a more uncommon 
item, that you have once in the current file and maybe several other times in 
the next files, the search function stops reporting new occurrences after the 
first

What version of the product are you using? On what operating system?
