[ct-user] How to make Super Check Partial work?

[John W2iD]

I tried invoking ct with 

CT ARRLDX -D   and also  with just   CT ARRLDX

Either way, my Check Partial window doesn't show any matching calls except
those I have already logged.  It seems like it might actually be searching
my master.dta file though (and I do have one in the CT directory), because
when SCP mode is enabled (by pressing F12), CT slows wayyyyy down when I am
typing a call into the callsign field.   When I press F12 to close the Check
Partial window, CT speeds right back up.

Anyone see this before?

Using CT 9.9.2.001 just downloaded from K1EA.com. 

Thanks,
