Everything works awesome so far!
I created the custom fields, created the custom content type, created "single-type.php" from the "Templates" section. When I click "New Type" in admin menu, the editor window opens like "Posts" and "Pages" as expected except for this one issue, the TinyMCE or WYSIWYG editor is like 2000 px in height...I have to scroll considerably to reach the custom fields..
any ideas why the editor window is so huge? I didn't see an option to customize the height anywhere...
