Some functionality problems may present when using Easy Projects .NET with Internet Explorer - drop-down lists are not opened, etc.
The first step when using Easy Projects .NET with Internet Explorer is to put your EP's URL into a "Trusted Sites" zone, which allows IE to not restrict the loading of javascript, setting cookies, etc.

The second step is to disable the "Internet Explorer Enhanced Security Configuration (ESC)" (Windows 2003/2008) feature as follows:
Control Panel - Add/Remove Programs - Add/Remove Windows Components
Internet Explorer Enhanced Security Configuration <- remove the checkbox and click Next.
