Hello Tech Support,
When using any version of Safari and when the BreakElement option is set to <br>, the current version of Cute Editor for ASP 6.6 still uses the <div> method.
This is also occurring on your demo area install of the RTE at...
http://cutesoft.net/asp/oncarriagereturn.asp?BreakElement=br
... while in Safari, type in a few lines while the <br> option is selected, and then hit the HTML preview button at the bottom, and the first line is left untouched, while every line after that is bracketed with <div></div>.
Also, on any of the demo areas on your site while using Safari, (and in my current version install 6.6 as well)...
http://cutesoft.net/asp/EnableAll.asp
... none of the drop-downs (h1, h2, font selection, css class size, etc.) seem to have any effect either.
Thanks for looking into this, I'm sure there's just a bit that's been commented out or something, but I have no idea where to look for it.
