I have a situation I have observed recently caused by the rendering in IE. This relates with the inclusion of a table which has a 100% property.
If you take a look at this page in IE, you will see that the table of the list of applications pushes the right side by several pixels.

This is related to the use of the 100% I use to have the table to take the maximum space in the content area. So far, in order to solve this problem, I had to force a fix width of the table. But, this is not what I want. As, if I change the site layout by a few pixels, I would have to adjust the fixed width back later. I need to preserve the 100% in there. I haven't been able to figure out why IE reacts like this and what can I do to avoid it.
