How do I update dims in drawing after changing dimstyle?

I seem to remember using _DIMSTYLE to open up the dimstyle manager and after changing a few things I had to update the parts of my drawing to reflect the new settings. I remember selecting all and clicking update.  How do I update my drawing's contents now?? I can click "Set Current" but there is no "update". Erasing my old leaders and text is becoming a pain.

Thanks for any help!
