The only thing I've ever found that Xy couldn't do is undo. I don't mean Undelete, but undoing operations. All modern programs have it. I wonder if it could be done in XPL? Even one level of undo would be great.Probably the most important undo would be undoing a Change Invisible.Hmmm. Maybe the way these things work is by aborting and restoring from a temp file, or a temp memory image. Anyone know how Word etc. accomplish the undo?Harry Binswanger hb@xxxxxxxx
