We are havinng the same problem using tables and images.  The images remain for a short while and then become misplaced/a mess and we have been starting all over again.  Also, most times when I try to create a hyperlink behind the image it creates it.... and then a short while later it appears with an unwanted frame around the image.  We were using the 4.0 version and are now using 4.5 and still experiencing the same probelm.  Please help..

Are you running the applications on XP pro?

If so, it has nothing to do with the Cute Editor.

XP Pro has a limitation of supporting 10 concurrent inbound connections. 

If you have a page called index.html & you have 20 graphics on the page, from IIS's Perspective, at least 21 connections will have to be made to the server.

Each time your browser hits a given page, it also takes 2 connections from IIS. If you have muliptle windows open, I can see you running into issues very easily.

If you keep refreshing the index.html page, first you will get broken images. Then you will get the following messages:

"403.9 - Access Forbidden: Too many users are connected
Internet Information Services "

Hope it helps.

Keep me posted.
