This ad for "Parallels Desktop 6 for Mac":
Needs to be reigned in. There is something in it that will not allow the site's menu-bar drop downs to display properly. It insists on being the top display layer and blocks access to the menu items. I have been forced to use content blocking on it so that I can get to the menus.
I am using Opera 10.62 on Windows XP Pro SP3 if it makes any difference.
