Using JQuery to enlarge the text input boxes in Sharepoint 2007 Blog forms

Question

I have a site set up as a Blog Template. I want to use JQuery to expand the size of the text boxes for blog posts in both Viewing and Edit mode (and new mode).

Viewing mode is easy. I edited /Lists/Posts/Post.aspx and added a CEWP containing a reference to Jquery and Code: jQuery('.ms-PostWrapper').width(800);

I tried to do the same thing in /Lists/Posts/EditPost.aspx and it doesn't work in IE. It works in Firefox but that just shows literal HTML tags.

So how do I get this to work in IE? I can see there's already some IE-specific Javascript going on. Any advice would be appreciated.
