Hello Adam,
I can't reproduce a problem we're seeing in our own application on your demo page because we use CuteEditor.EditorResizeMode.AutoAdjust and the demo does not. I see the issue I'm referring to frequently.
When I make an edit to the content I'm working on under CE, whether in Normal or HTML mode, I'll sometimes see the page begin quivering endlessly. It appears that it's because the window is continuously shifting between having a vertical scroll bar and not having the scroll bar. While it's in this mode, it's very hard for the user to click on anything in order to stop the behavior (though using F12 to go to full view mode resolves the issue). I then have to make some random edits before I can switch back to small screen mode at which point the quivering problem may or may not have disappeared.
If I copy the offending HTML (while in 'quivering' mode) and paste it into the demo page under the same browser type/version, I don't see the quivering problem. Yet, if I close and then reedit the content page locally it continues the quivering until I make the appropriate random edit to stop the problem. I haven't yet figured out what the specific tags are that lead to the problem, though the removal of characters (inserted by CE while I'm editing in Normal mode - especially if I backspace/delete and then continue editing) from the HTML usually seems to remedy the problem.
See the video below which exhibits what I'm talking about. [Note: I tried uploading the video both with IE and FF and each time I tried, the Insert Media pop-up upload session hung (requiring me to kill my browser session)..] Thus, I'm unable to show you the video that I wanted to show you.. I've tried numerous times and it usually hangs at between 7% and 10% uploaded. It's an AVI file that's 5,572 KB in size. Can I email it to you?]
Regards,
Kazzlo
