Probs when viewed in mac

[Roma]

Hi,
There is a problem in viewing a few pages on the site that i have designed.
http://www.pharmquest.com/corporate/Html/newsroom/news/list_news.htm

In mac the text& the image table on the middle of the page goes & sits at the top of the page...on the banner image there...
Morover this happens only in pages there are no images in the table below...the page below..shows up perfect.
Eg..http://www.pharmquest.com/corporate/Html/products/overview.htm

Those pages looks perfect in IE & netscape in PC. & also looks fine in netscape in mac...

Can somebody please help me to fix the bug...

Thanks
