I've been using Fldigi for quite a while without any issues. Recently, however, and seemingly all of a sudden, the callsign window will not retain a callsign. If I click on someone calling CQ their callsign pops into the callsign window as it should but it disappears after 3-4 seconds. I've tried all kinds of tests in configurations but no dice. When I make a contact and then attempt to RETURN to that person, their callsign is no longer there. I'm using the latest program, version 4.1.18. Has anyone experienced this situation? Thanks, 73 Steve

Solved the problem, had both programs "fighting" each other to open QRZ-Lookup. Deselected AClog from the lookup and selected Fldigi. Now it all works. It was like trying to park three cars in a one-car garage.
