For the record I wanted to add what I found and how I solved the problem. Thanx to those who advised me. Firebug proved to be a very useful tool and it showed that the CSS classes with CF9 are quite different than with CF8. It turned out that cfwindows in CF9 (unlike in CF8) open without any padding or margins, so generated HTML is flush to the upper left corner. (In CF8, there is a 10 pixel pad around the work area).
To restore this 10 pixel pad in CF9, the simple solution is to change the CSS for the class: div.x-window-mc I used the following in my style sheet and it is now consistent between releases: div.x-window-mc {font-family: Arial, Helvetica, sans-serif; background-color: #ffffff; padding: 10px;} ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Want to reach the ColdFusion community with something they want?
