I pressed SPC to see the MIME part header, then clicked on it, and moved the mouse over the expanded attachment text to highlight it, I then pressed SPC a couple of times to scroll the buffer, and pressed DEL to get back to the MIME header - and clicked it .. and the last line is shown three times. And there are lots of mouse-highlight artifacts. This is probably a problem with scrolling through multiline mouse-hightlight which spans multiple pages. Chong, could you take another look at it? -- Kim F. Storm http://www.cua.dk
