what browser is it changing to if IE7 is the only one? and which one do you want set?
Not told
Everyone having IE know what i mean. There's an option to check in IE, to be alerted if IE is still default browser when launching it.
Though, even if i don't get another browser, as i mentioned, each time after having launched Impulse, when i launch IE, i get the message that IE is not anymore the default browser (that's why i think there's a browser in Impulse which is set by default ... as simple as this.)
N.B: BTW 1°) in my initial post is for me more important
