No you are correct. I checked and we are using v7.3.5 I have downloaded v7.3.6 but there are many breaking changes.
For example, where has the XHTML property gone? and where has the .Toolbars property gone. I used to do something similar to the code below but now this wont wort and replacing .Toolbars with .Tools doesnt work either.
Is there a list of breaking changes somewhere?
