Edit.Top is anchored to Label.Bottom. Label is invisible so the LCL goes to the anchor of Label.Bottom. Probably you did not set a Label.Bottom anchor, so the LCL found a dead end and just did nothing. Now assumes the label.top is anchored to another control A. If A is moved then the Label and Edit should move too. With old behavior the Edit is not moved when the Label is invisible. With new behavior it will move. You can get the old behavior by doing: Edit1.AnchorSide[akTop].Control:=nil; Label1.Visible:=false; Mattias _________________________________________________________________ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
