canvas disappearing in applet

I have a canvas with a drawing added to a Panel on my applet. I posted the applet on my website, when I visit the site, after the page is refreshed, the canvas disappears. Also, once I've opened Safari, if I revisit the page, the canvas won't show up at all, but when I quit Safari and reopen it, it shows up again until the page is refreshed. Does anyone know why this is happening?

Thanks,

Jamey
