Hi Adam,
While evaluating the cute Editor 6.2 and going thru the link you specified, I found it works in IE 7 only and not on other browser)FF,Netscape,safari etc)
See the imagebelow, when tried to insert youtube it had inserted flash image. but in HTML mode I can see the Html that I tried to embeded.
I have used following string using insert youtube option.
<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/LLhRtV1xKiM&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/LLhRtV1xKiM&hl=en&fs=1" type="application/x-shockwave-
flash" allowfullscreen="true" width="425" height="344"></embed></object>
If you have any solution orget around it will be great help to decide.
Thanks
