But can't give you much more info. This kind of thing will work on auto generated calc sheets with insane amounts of data. So expect an improvement of ~ * 1.4 on the sum plus the time spended on the interpreter.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
