I'm having trouble with change length today: close just ignores me. It sometimes succeeds on the second or third try, but other times it just fails altogether. I've triple checked that I've correctly clicked 'ok' and not 'cancel', but it previews the action only to revert to the original line length once the dialog box is gone. I can move the point manually, but it doesn't afford me the degree of accuracy that 'change length' does.
