Hi Joe, As the captioned subject says. When SafeOnline module in Prevx facebook version .185 is active (regardless a browser, in my case Opera 10.61 and IE8 ), right clicking on speaker icon in systray and choosing Open volume mixer triggers the crash of Volume Control Applet. However when SafeOnline is disabled no crash occurs. I am sending the Microsoft's crash log and Prevx's scan log to firstname.lastname@example.org with a link to this thread. Thx for resolution and regards, pegas EDIT: I forgot to say that before you go to open the mixer you should play in a browser something (youtube etc.). It looks the crash is tied with playing sounds.
