Hello!
Thank you - that worked.
Just in case anyone as clumsy as me follows this, I think what went wrong was....
I created my original layout by slicing up a Photoshop image.
This resulted in lots of merged and split cells.
I added a bottom row and merged the 7 or 8 horizontal cells together to make one.
I then decided to simplify the cells above, and replaced the patchwork by merging.
This gave me one simple row of cells for content.
Somewhere in this process the cell width for that bottom row I added must have got confused.
The result worked fine in most browsers... but not MSIE.
So thanks to Bluedreamer I deleted that bottom row, added in a new row, merged the cells horizontally, and hey presto.
As always with even the simplest of mistakes it's difficult to know exactly went wrong without watching all the mouse clicks, but thanks for spotting how to put it right.
I'm going to finish of the table based site and then see if I can get anywhere with the DIV based site... doubtless I'll be back!
Dave
