This is an html or browser question but I would appreciate if someone can advise on this.<BR><BR>I have an application with 2 frames. The frame on the left hand side contains a number of images which act as buttons to activate different pages displayed on another frame in the middle. onmouseout and onmouseover events are fired on these images so that images are swapped to make them look highlighted when the mouse cursor is over them.<BR><BR>Here is the problem:<BR>It happens quite often that when an image is clicked on, some images (sometimes all) in that frame disappear. I can make them reappear by moving the mouse cursor over them to fire up the onmouseover event. But when an image has no event, it just disappears. I have seen the same thing happen on some other sites but I don't know how to correct this.<BR><BR>Any input on this is greatly appreciated.
