link column type with mailto

The following string stored along with the java string inside a dhtmlx grid cell works fine “^javascript:frm.action=“PropertyGenInfo.action”;frm.submit()^_self” ,but when I append “^javascript:mailto:xxx@yy.com” string,the link leads to a empty page rather than invoking configured mail server ( for eg outlook express)

smtp server already configured and works fine oustside the grid

Could u tell me how to resolve this ?

Thanks

Just use: Email me^mailto:some@some.com
