  states:
---------------------------------------------
User-Level Certificates
Options

For Trusted, Secure site, and Client Authentication certificates, there are four options: Import, Export, Remove, and Details. The user can import, export, remove, and view the details of a certificate.

For Signer CA and Secure site CA, there is only one option: Details. The user can only view the details of a certificate.
---------------------------------------------
However, the buttons " import,export,remove,details " for the " user " tab ARE all enabled for the certificate types " Signer CA " and " Secure site CA " .
importing does function(i.e. it appears in the list), but at runtime this entry doesn't seem to have any effect on webstart ssl handling.
