I am using Ajax Q2 controls (beta) and when displaying a RadEditor inside of a MultiPage/Pageview set to 800 pixels (and the Editor is also set to 800 pixels), the editor displays at runtime at about 100 pixels wide. This problem occurs in IE, Chrome and Safari. Even though, the Safari and Chrome are the worst. Interestingly, I have a couple of instances where the Editors do appear with the correct width.
Actually, after some more testing I realize this this problem even exists in the designer, not just runtime. If the editor is set to resizable, you can stretch the width to the correct size, then it will not let you shrink it past the pixel width set in designer.
For some reason, I have one editor control that is not affected by this anomoly. Not sure why. I even tried copying and pasting the "good" control onto another page, thinking that maybe there was a property set differently, but the editor still does not render correctly.
Any ideas?
