Layout Issues with Site Sculptor site

Hi,

I have upgraded to DE and since have attempted to define a new site using the entire system, I am able to create a customized design the client wants usign a 2 col hdr ftr layout, (left column). All works fine the layout is created and displays fine with the Power CMS content in the left col and content div's, I removed the sidebar PowerCMS content and replaced it with a vertical menu in the left column using CMS MW successfully, again this displays correctly while the pages contain the PowerCMS default content in the content div. I then attempted to add both custom and a simple contact form (on different pages) and while they continue to display normally in IE, when tested in FF, Chrome or Opera the form displays after the end of the left column. Remove the form (not the validation script links or css links) and reinsert the power cms content and again all goes back to normal layout. Are there any know issues causign this or am I suffering from a unique illness?

I have checked the widths of all the div's and the CSS MW widths and all were within the correct parameters, but I still attempted to decrease the width of the content div and leftColumn div to see if that would change the layout with no success.

I look forward to your solution making me realize, once again, I should have seen the answer myself. Any input to ease my pain would be greatly appreciated.

Regards,

Gary
