[CLOSED] Portal Resize Ajax Event fires on page load... not just on the resize
I am trying to capture the resize event on a portal, but it seems to be firing on the page load and also when the tab is clicked on (activated), this is causing my to record some incorrect values for the width of the portal in my database. Is there a way to keep my resize function from firing unless the portal was resized by dragging the mouse?
