What is "deltags.pm"? Is it a freestanding version of U2 frame DELTAGS?Yes. For my wife's use, before she had U2 (and she's kept using it).But the problem seemed to be some sort of system state that is gone now. Very strange, but perhaps the system got into trouble when I was experimenting with wildcard search & replace, which seems to put a strain on things.At any rate, quitting and re-launching Xy stopped the error! Thanks for looking into it. Harry Binswanger hb@xxxxxxxx
