Right clicking on tray icon opens a menu that is blank. Clicking on it does nothing. So I double clicked on icon & Xolox opens but top buttons are missing, it's frozen I guess. I had to go Ctrl-Alt-Del and indeed it was not responding. I'm using Win98 SE, modem connection 56K. Circumstances: I first got online with 1 unfinished DL that found a host for 3% more (big file) then it went searching for new hosts again. I then DL'ed a short MP3 which went OK; then I got offline; and when I got back online the problem was there.
