Multiple Appeon applications cannot be run in the same Internet Explorer session. You will find more information below:

With IE 7, it is unsupported to tab browse multiple Appeon applications deployed with the same Appeon version, as all tabs are sharing the same session in IE 7.

With IE 8\9\10, by default, you can run no more than two Appeon web applications in different tab pages, or different IE browsers.  If you want to run multiple Appeon Web applications (more than 3) with IE 8\9\10, you can:

1. Click the New Session item on the File menu of IE 8\9. Then access Appeon applications in the new opened IE browser.
2. Run iexplore.exe with the -nomerge parameter so that whenever you open a new IE browser, new session will be created. For example, you can change the shortcut of IE 8\9 to "C:\Program Files\Internet Explorer\iexplore.exe" –nomerge.
