Works for me, steps I tried:

1) Open the attached file in the editor
2) Double click on ch-01-1.html
3) Move the cursor around and perform various minor edits in that file
4) No freeze

Is there some set of steps I can follow to reproduce?

I have a feeling that it might be too many processes running at once
- formatting file preview
- spell check (in editor)
- formatting (color) in editor
- search & replace (all files)
- ...

Try opening subj-index_03.html
then do an immediate global search & replace
then save.

(maybe my computer is to slow i7-2600 3.4GHz 3.7GHz 16GB RAM)

Note that when the editor hangs it still uses 6%-9% of CPU

Sorry, hanging when I got further in the file
Due to impatience and not waiting for end of formatting. If I wait till all formatting is complete it does not seem to happen

Cant get it to hang for me, steps I tried:
1) Open subj-index_03.html
2) Perform some edits on the style for .hi p
3) Add class="hi" to body
4) No hangs though it takes a little while for highlighting to resync after editing the body tag

Try editing at the end of the file.
May have something to do with the CPU speed
Something has definitely changed between 4.20 & 4.21
Formatting seems to take a lot longer in 4.21 and at least on my computers (portable & desktop) it hangs
Have rolled back to 4.20 on both and problem disappeared on both machines.
