As main browser my customer use IE8, running in Compatibility mode.
In my site we have added <META HTTP-EQUIV="X-UA-Compatible" CONTENT="IE=8"/>
Works as it is supposed. When my editors open CKeditor, the editor runs in Compatibility mode.
We have tried to add <META HTTP-EQUIV="X-UA-Compatible" CONTENT="IE=8"/> into the iframe but did not change the behaviour for the browser.
Any ideas on how to proceed?
