hpl123 Support, This is a bug report and the bug is that a empty space/area is placed under the imported html in the banner frame (not settings issue or html code issue). Wink bug report sent. Thanks
hpl123 Update. Heard back from support and this was not a bug but a change in Aware IM (5.9 > 6.0). The solution is to not have html and body tags in the html page imported in the banner frame (i.e only for example table). Havving these tags in previous versions still work.
