values not saving

Ok, i had this working fine a month ago but i’ve been heavily chaning my site, adding “plugins” and what not… and i just went to test everything and somewhere along the lines my geo setup got messed up.
I’m running WordPress 1.2 Mingus.
I have it set so that in every post it displays a link that says “where’s ahren” and the url for the link points to mapquest and uses the lat & long values to display a map of where I am…
Here’s the problem. When i try to compose a new blog, and enter in my coords, they aren’t saved. I’ve tried typing and then hitting Publish, tried typing and hitting save, and tried typing and hitting save and continue editing… none of them save the values. Unless I do it twice.
If i go into options and set a default value, then it shows up when i try to post and the link works fine… hippity hoop. However, if i go to type a new post and try to edit these, the new numbers aren’t saved… unless I do it twice…
I’ve uploaded fresh copies of post.php and edit-form-advanced.php and it doesn’t help.
Basically when i’m at /blog/wp-admin/post.php it won’t update the values… until i try it once and the url changes to something like: /blog/wp-admin/post.php?action=edit&post=87
Do you have any ideas of whats up?
