HIE!

i have a web page  which is full of tables.all widths are in 
percentages.but still whenever i increase the text size using IE's View-
>Text Size>Larger option my table details overlap each other and look 
really messy.Could you please help me as to why this happens and what 
should i do to correct it?

The site is best viewed at resolution of 600X800.When the page is viewed 
on a high  resolution of 1024X768 a whole column on the side disappears!
Please help me!!

Thanks!!
