Measurement Options Window has disappeared?

OK, I've been using my laptop with a second screen (Left right orientated) with SW2010, I was annoyed how the measurement options dialog box would always appear on the other monitor from where my Solidworks window was, now it doesn't appear at all, where has it gone?

I get the result from a measurement query OK but I'm stuck with the default unit and precision.

Last week I thought I'd found a solution in this forum, something involving a registry edit but alas 30 mins of searching now and I've found nothing relevant. Can anyone point me in the right direction of offer a solution?

Regards
