I took a look at Speed ->Transfer History. For me, it is switching itself between "upload+download only" and "uploaded only". And after a few "rounds" it turns ALL lines off for a minute or so... Of course, the linecolors in legend, which are not displayed, are grayed out. In case it matters, I'm doing Force Re-check of a 88GB torrent, which consists of many files. Another interesting glitch: When you highlight a row, almost all values in columns are shifted 1 px to the left. //Win7 x64 Ult
