Repainting image does not work

Question

Hi, I have this repaint() problem. I have a timer that calls the moveM1() method which updates the currentX_M1(X position of fly), and then repaints it. However, the fly isnt repainted to its new coordinate even if the currentX_M1 is incrementing.

If you are talking about the single rollover on that page you linked, it's a bog-standard rollover that will work in every browser.  Can't imagine why you are having problems with it.
By the way, the values for the name and the id attributes must not contain spaces....
