Stan,
I designed a new compound filter, not over large, for skimmimg off unlikely tickets, when I went to save it both the progress bar and program froze. I had no option than to stop EL via Windows Task Manager. When I restarted, I received an error message stating that EL was unable to load the compound database, I have lost all my compound filters. I have attached the error log, in case you can find something or maybe it was a glitch. :-/
