Engineered Software websites endeavor to support a wide-variety of web browsers. In some cases, however, it is necessary for certain sites to require more modern browsers for full-functionality. In these cases, the sites will often present users of older browsers with a message indicating the minimum supported browser.
Unfortunately, even users of modern Internet Explorer browsers may occasionally see these compatibility notices. This happens when "compatibility mode" has been enabled in the browser, forcing it to render the page as if it was an older non-supported browser.
The good news is that so long as you are running in a supported version of Internet Explorer, disabling compatibility mode will make those messages go away and may also improve your website experience.
Managing Compatibility Mode
Depending on the content of the page, Internet Explorer will sometimes display a button next to the address bar indicating whether or not the current page is being displayed in compatibility mode. If the button is there, simply clicking it will toggle this mode on or off.
Compatibility mode is ON.
Compatibility mode is OFF.
If the compatibility button shown above is not displayed and you're still seeing incorrect compatibility notifications, then the website is probably being forced into compatibility mode by an internal browser setting. We can easily configure this from the "Compatibility View Settings" dialog.
Launch the dialog from the "tools" menu. If menus are not enabled in your browser, press and release the "alt" key to temporarily enable them at the top of the window.
In the dialog, look for the check box labeled "Display all websites in Compatibility View." If it's enabled, then every website you visit is automatically rendered in an older format. Uncheck the box to allow the website to specify how it should be displayed.
Finally, if the above check box is not set, look through the list of "Websites you've added to Compatibility View" on the same dialog. (It should be short.) If you see the website you're having trouble with in that list, select it and click the remove button.
