font navigator can't check boxes

I've had this problem before in font navigator, but with this latest version and new system I thought the problem would have been solved.

I tried having font navigator recheck for new fonts, well I can't put a check in any of the boxes, so it won't search for anything.

anybody else have this problem?

finally got this fixed, if you're using a multi screen setup on your machine, make sure fontnav is running in the primary screen, otherwise the check boxes don't work. You can just open it then drag to the primary and it works.
