[Dx4win] callsign search filters

[Mm0eax at aol.com]

Hi All
   Just upgraded from 6.04 to latest version 7.01, has anyone  noticed that 
the search patterns in "prefrences-qso" have no affect at all  regardless  of 
whether they are set to fuzzy, pattern, exact or substring!  they all have the 
same effect ie: exact callsign must be entered in callsign  field before 
finding anything?  Or am i missing something?
