[Dx4win] Search for all QSOs with a "Frequency" filled in?

[Lee Hallin]

I am probably missing something obvious!

Using DX4WIN v9.0.9.1259, I did a F8 and, in the Frequency field, tried
entering an "*" or "!" but it beeped at me.  It acts like only numeric
digits (and .) are acceptable.  Is this true?

This isn't a "show stopper" since I can export to a .DXQ file and then scan
the Frequency field for non-blanks.  Was just wondering if there is a
simpler way!

Thanks & 73,
