Hey Isaac,
So far I've been using Mozilla to test my page. I had just tried in IE
6 and I see that when I hover over a row, the columns to the right of
the first one end up disappearing until I resize the column or the
window or something, then again disappear as soon as I hover into the
table. When I drag to resize the column onto the left, the second
column shows up. Has any such behaviour been encountered, any reason
or solution for it? Just checking to see if this was a common thing.
Thanks
Suri
