jquery and the activeX control in internet explorer...

hallo everybody, i m a real newbie in javascript and jquery..
till now i was working with flash and html+css, now in going to do something with jquery..
I have a question about the activeX control in IE, because i can see that all the esample in the Jquery website they work great in IE, but i have made a simple animation that move an image along a line with Jquery, and every time i get the activeX control pop up!!
So i would like to unterstand why this happen, it will be great a quickly solution.. but in any case if there are already some tutorial about this, also for Javascript itself!!!
