block placement does not work as expected

Block placement does not seem to work anywhere but the left_sidebar. I am creating my own template (very simple right now just .tpl files). I also tried this with the cvs version of box_grey_smarty.

I am getting weird behavior like:
- add latest image block to header. This works fine in bluemarine, but ends up moving my primary links to the header (in a smarty theme). The primary link block is in the header for any smarty theme now. Even after there are no blocks in assigned to the header.
- I can not get anything to show up in sidebar_right. I added a smarty {debug} to my template and the variable is assigned, but empty.

Setup:

• I disable caching
• I tried copying my theme to a new directory to make it get recompiled
• Using drupal from cvs (Feb 7, 2006)
• Using smarty-engine from cvs (Feb 7, 2006)
• Smarty libraries = 2.6.11
• I get the same problems under php 4.3? and php 5+

I am a little suspicious of the admin/block code. I think you used to be able to specify different blocks for each theme, but that seems to be broken now. However, I can move the blocks where ever I want under bluemarine.
