I bought the ASP component a couple of days ago after convincing a client who uses a Mac that this would be compatible.
First of all it only works in Firefox on the Mac and not Safari (and to a lesser extent IE 5.2, but nothing works with that!) which is a shame. Secondly, as the above user has posted, the break element doens't work in Firefox as it always defaults to <br />. Thirdly, the paste from Word/clean HTML options do not even show in the toolbar (though the editor I am typing this thread into which appears to be the .NET version has the button).
So far my client while impressed with the editor itself, finds his most common tasks (not have to use a PC, make correctly formatted content with paragraphs and pasting content directly from Word documents) don't work. I hate having to say "This is just another thing that only works in IE 6", as points 1, 2 and 10 on your Features and Benefits of the control aren't valid when not using that browser.
Any ideas when/if there will be an update that resolves these issues?
