I'm having problems with MPC-BE. If I check the "use the preview in the search" box in Options>Interface, I get the preview when I hover over the seek bar, but no picture in the main area. If I uncheck it, I get the picture, but no preview. Can anyone suggest what's gone wrong or how I can fix it?
I'm using Windows 7 and MPC-BE version 1.4.4 x64, (build 27) beta, but I've tried earlier versions with the same result.

Thanks.

David
