I attached the Open Browser Window behavior to a thumbnail photo directing it to open a linked page in a new window to show a larger photo and description. This works fine using the default onMouseover event. I altered the event from onMouseover to onClick. Upon clicking the new window opens fine, but the original browser window (with the thumbnail photos) also loads the page being loaded into the new window (in IE4 and NS4.75). Any suggestions on how to make it refrain from loading it into the original window as well?
