Access Denied incorrectly received when posting code snippets

Hi,

I'm trying to post a blog entry (roller 4.0.1) and getting an erroneous 
Access Denied error indicating I don't have permission to access 
http://x.x.x/roller-ui/authoring/entryEdit!save.rol

The problem is clearly related to the contents of my entry because if I 
leave out part of the entry I can save it as a draft.  But trying to 
save the full entry causes this error.  I am trying to post Java code 
fragments and XML fragments.

Any help trying to get past this would be appreciated.
