Imagecache..module insert module...clickable thumbnail->original , duplicates why? pic inside

So I have tried doing this according to forum user "ANTI"
_____________________________________________________________________
The 'best' (ie. easiest solution for the user) I have found so far is:
· cck + imagecache + filefield + imagefield for uploading the image to a folder.
· insert module for inserting the uploaded image into the wysiwyg editor window.
· And if you want a really smart finishing touch, the image resize filter module.

Here are the module pages:

http://drupal.org/project/filefield
http://drupal.org/project/imagefield

http://drupal.org/project/insert

http://drupal.org/project/image_resize_filter

But Im getting this annoying duplicate picture all the time. I have tried for 2 days without sucess! Getting tired of this. I hope someone can explain how to fix this.
Let me guide you what I have done.

1. Installed a whole new drupal with wamp with a new and fresh database
2. installed cck, imagecache, filefield, imagefield, insert and image resize filter
3. Installer TinyMCE and WYSIWYG
4. Went to Imagecache and preset a thumbnail setting 166x166, save
5. Installed blogpage
5.1 installed Shadowbox (have almost the same function as thickbox )

6- Went to Home › Administer › Content management › Blog entry and added new field (field_imagecache, type:file, widget type:image)
6.1 I choosed that the user can input: Thumbnail, autimatic and original img.
7. Ok so good so far. When Im trying to upload a image and insert it to the text editor, a small thumbnail are showing upp. But when saving and me trying to click the thumbnail, nothing happens.
IMO the thumbnail should expand using shadowbox and show the original big size pic.
8. So I tried to go to Home › Administer › Content management › Blog entry-> display fields.
From here I choose Above: Shadowbox: Thumbnail to original (this is for teaser), and for full node I choosed Shadowbox: Thumbnail to original , then save

9. Now when uploading a pic and insert as thumbnail I got 2 duplicates, one above which isnt clickable and one under the unclickable pic that IS clickable and expands to the orginal size.
So it seems that the duplicated clickable thumbnail works as I want, but why is it a unclickable thumbnail above it?

IM GETTING CRAZY SOON ;)

When clicking the image below it looks like this

And this is exactly what I wants! But having the duplicated unclickable pic above are confusing

Summary: How do I remove the UNCLICKABLE () imagecache and have the CLICKABLE imagecache still?
