1. The problem with non-rounded bottom corners is actually a bug, I didn’t figure it out earlier when I read Jasmin’s comment.
If you can modify the theme, please open functions.php file and replace the number 265 with 281. And then upload a header image with dimension of 500px in width and 281px in height.

2. Double up on page links problem is a known issue (other user reported it before) which I could reproduce but still can’t figure out what’s causing it and what’s the proper fix.
The workaround is to create a custom link to a website that is relevant to your blog. On the admin screen, on the left sidebar, there’s a section Appearance -> Menus, add custom link to the default menu, then save the menu. The double up will then disappear.

3. The inconsistent sidebar heading sizes are caused by some of the widgets have heading title with h2 tag, while some others use h3 tag.
Try checking if those widgets allow you to change the heading tag. If not, then you need to change the stylesheet.
Open styles/style.css, add this at the bottom of the file:
div.right h2, div.right h3 {
font-size: 13px;
}
Change the value 13 to the size that you want.

Hope that helps.

just migrated from movable type to wordpress, and very pleased with this theme. however, i’m having some minor issues, including the same one as Jasmin. when i use the default header image, i see rounded corners on top and bottom. when i upload my own header image, however, i get the squared corners on the bottom — regardless of whether i upload a larger image and crop it, or resize it manually to 500×265 before uploading. i’m using Camino 2.0.6 on Mac OS 10.6.6, but i have the same issue with Safari and Firefox.

two other minor things:
- if i leave the header left sidebar free of widgets, it defaults to the Home, Feed, etc. links, which i really like — but it includes pages I created twice (in this case, just About).
- on both of the right sidebars, the size of the title font is showing up inconsistently. right now, for example, “Categories” is smaller than the title of my Archive and Recent Comments titles. Doesn’t seem to matter if I create my own title or use the default.

thanks!

The rounded corners are styled in style.css file, look for div.splash .

If you only want to remove the header image, the easiest thing to do is to remove the header.jpg image in the theme directory.

If you want to remove the whole header section, for version 1.3.3, you need to modify certain lines in style.css file:

div#header {
// position: absolute;
// top: 10px;
display: none;
}
div#bodyfooter {
// position: relative;
// top: 350px;
}
