Hi, it is not much changed.

Same error when changing font size/color/name:

Line: 3<br>Error: Object doesn't support property or method 'containsNode

Find dialog now opens but when you click 'Find Next' now I get:

Line: 1<br>Error: IndexSizeError

Insert Image Dialog seems to be repaired.

Test HTML generated from me typing a line of random text and clicking a few buttons:  (have to enter a few fonts/colors/sizes before the errors start happening)
