Windows 8 has 2 modes: Metro and Classic. Internet Explorer version 10 (IE 10) is the default browser of Win 8 and can be played in Metro and Classic modes.
Adobe Flash player is also integrated by default on IE10 and is configured to work differently on Win 8’s Metro and Classic modes.
Some courses on Coggno are Flash based, and they might not play correctly when using IE 10 in Metro mode.
When your Operating System is Windows 8 and you are using IE 10 browser, please use Classic mode (traditional desktop mode).
