The error shows up when I am on Facebook and some opes an instant chat. Also when I open the window that lets me listen to my fav radio station live online and and sometimes when downloading something. It never did it when I used Internet Explorer now i use Firefox. In the most common case, its in Firefox. The window banner reads: Microsoft Visual C ++ and states,Runtime ErrorProgram: CProgram FilesMozilla Firefoxfirefox.exeR6034An application has made an attempt to load the C runtime libraryincorrectly.
