[Dx4win] Problem Exporting All QSOs in the log file

[Larry M. Leitch]

Here is what happened when I tried to export my entire logbook to LOTW.

File...Open...K3FIT                                           //open my 
regular log book
QSO Window...Filter...Cancel Filter                  //clear filter
QSO Window...Labels...Set Upload Flags         //set all upload flags

Dialog -> 1804 QSOs changed                          //response from DX4WIN

QSO Window...Labels...export for LOTW        //export all

File...Save As... select filename.                         //save in 
this .adif file

Dialog -> Export Finished No QSO Written      //no QSOs saved??? why not 
1804???

Dialog -> Error                                                  //why 
this???
   An exception occured!
   Access violation at address 005B16D1 in module 'dx4win.exe'. Write 
address 4F344D71

At this point, the dialog Import / Export Filtes can not be dismissed. 
//hung
The Import / Export File..Exit pull down has no effect.
The only way to dismiss the dialog is File...Exit from the main window.

Help!
