stretch77 found another post somewhere (pleas paste a link, btw) that suggests that upgrading to flash 10 might help solve the problem. Below are some lines of code that will facilitate the upgrade. Note that since Adobe doesn't provide a Debian/Ubuntu package, the following lines will fetch the Red Hat package, and convert it to something Ubuntu can use.
Please note that Flash 10 is still Beta, so YMMV (Your Millage May Vary).
sudo apt-get install alien
wget -c http://download.macromedia.com/pub/labs/flashplayer10/flashplayer10_install_linux_051508.i386.rpm
sudo alien --to-deb flashplayer10_install_linux_051508.i386.rpm
sudo apt-get remove flashplugin-nonfree
sudo dpkg -i flashplayer10_install_linux_051508.i386.deb
