Can someone explain me the reason of a strange behavior? The following code doesn't clean the "area" field. Just press "valorize" and then "clean". Thanks. REBOL [ ] Preview-form: layout [ button 150x24 "valorize" [valorize] testo: area "testo" 700x200 wrap below button "clean" [clear testo/text show testo] ] valorize: func[] [ testo/text: {<titolo>12234567891 asdfg, asdfghjk - aswedfrtg azxcdftre dsr gjftptyf <p> lkdjflkdsjflkdsjflkdsjflks flkdsjflkds flkjdslkfjdslkf lkdsj flkdslkfj dslkfjdslkj flkds fkds flkslk fjdslkjflkds flkdj fklsd } show testo ] view/title Preview-form "Test"

Someone explained it before, and made a better solution. For now, you can do this: button "clean" [testo/text: copy " " show testo] and also, you should valorize: func [][ testo/text: copy {<titolo>122345... Actually, I think I remember now. Something to do with testo/line-list not being cleared? Umm... Need to check older mails about a week ago...

Something even more interesting happens when you use this code for the clean button: button "clean" [testo/text: copy "" show testo] Seems you can peek through rebols memory as you push it repeatedly. Kinda fun. Anyhow, my explanation is that its a big fat bug, and a good excuse to use feedback. --Ryan Luca Truffarelli wrote:

Yes - one of my mails - but I'll save you the search. This is from the View guide... line-list: A BLOCK that is used to track the offsets of text lines when text is being displayed. When more than 200 characters of text are being displayed, this list should be set to NONE when large changes are made to the text. This allows REBOL to recalculate the locations of all TEXT lines. So, adding... testo/line-list: none before show testo should fix the problem. So, a bug Ryan? Hard to say, but it has the feel of a work-around of a bug. (:

Thank you to everybody and excuse me if I haven't answered you before. :(
