buttons don't change content in tinyMCE fields in IE10 – possible fix

On initial page load, the correct content is displayed in fields that have the Visual Editor enabled. After page load, if you use the language buttons, the content isn’t changed for the fields using TinyMCE.

Not sure if this is actually a bug (maybe someone can confirm) or some plugin conflict BUT, after hacking away at admin/js/common.js I discovered the following:
– window.addEventListener('load', function(){ ... }); works to register tinyMCE.editors in Chrome but not in IE (weird?)

– “I have no idea what i’m doing but it’s fixed”: wrap everything up from inside the ‘load’ function in a setTimeout() with 1000 to give IE a chance to “LOAD” load the loaded page. (sheesh)
