Many of the editing options of the online calendar are done through pop-up windows. Editing or adding and event will bring up a pop-up window that will allow you to customize the event. If you have a pop-up blocker running on your machine, it could be preventing those editing windows from displaying.  
  
Common programs that contain pop-up blockers are: Google Toolbar, Yahoo Toolbar, MSN Toolbar, MyWebSearch Toolbar, some virus/firewall programs, and Internet Explorer now come with a built in pop-up blocker if you have upgraded your computer to Windows XP Service Pack 2.
  
The default settings for Internet Explorer's built in pop-up blocker do not threaten our calendar; however if you have increased the security settings on your pop-up blocker, it can prevent our editing options from displaying. If you need to change the settings of Internet Explorer's built in pop-up blocker, go to the tools menu in Internet Explorer, locate  the "Pop-up Blocker" option, and select the "Pop-up Blocker Settings" option from the side menu. This will allow you to configure the settings of the pop-up blocker.
  
So please ensure that if you have a pop-up blocker installed, it is configured in a manner that will allow our calendar to function properly. Because there are so many programs that have pop-up blockers, we aren't able to provide information on how to configure each one. Please consult the help section of your pop-up blocker program for detailed information as to how to configure your settings.
