file name

When creating a vCard, the module doesn't produce a proper file name, but all you get is <.vcf> (i.e. there's nothing in front of the extension).
VCards open fine through Firefox v3.5.3
IE v8.0 struggles to know what it is that is supposed to be opened, as IE displays the file as <.vcf[x]> (where x represents a number assigned to it by the system after you have already opened another vCard).
