You may post here if you are having problems with Winlog32 that others may be able to help you with. You may also report bugs so that the author may act upon them.
Maybe easier to export the required QSO using the SEARCH LOG and EXPORT SEARCH functions?
Menu/Search/Search Log/
In window paste following query (and then EXECUTE button):
SELECT * FROM LOG WHERE Remarks LIKE '* [#]IT*'
If your log is not called LOG then this may be changed
N.B. the hash character # must be enclosed in the square brackets [ ] as example, as this is a SQL pattern matching character and to work it must have brackets around it. Note also use of the pattern matching character *
Once you have found QSO in Search WIndow - you can export this using menu/File/Export/Search/ADIF
