InfoPath Dev

I have a infopath 2007 form that I have created using visual studio 2005 (C# code)  and published to a infopath forms server. the form has digital signing and submission features.

My problem is that i am unable to save the form. The toolbar at the bottom and top of the form does not have the Save link. I have checked off all the toolbar options in the Tools->Forms Options->Browser category but the Save link does not come up.

Has anyone seen this behavior?

thanks

Check the permissions on the forms library

 in the tools -> formoptions -> open and save

make sure Save and save as check box is checked

also 

in tools -> formoptions -> open and save -> browser 

make sure Save, Save as checkboxes are checked.
