By now it looks this way:
WebView1.Top = 12%y
WebView1.Left = 0%x
WebView1.Width = 100%x
WebView1.Height = 70%y
Could be this way:
WebView1(12%y, 0%y, 100%x, 70%y,,,false,,,,true)
False and true in this case are not making sense, only for showing, that there could be other unused options inbetween...
Hope it's more clear now. Sure, first look is not easy. But you can faster and exactly find the point, where to change something. Jump into the line during editing and a small declaration of syntax could pop up, as when writing program code.
