Please fix code.

At file syntax-highlighter-compress/tinymce/window.php

Find

window.tinyMCE.execInstanceCommand('content', 'mceInsertContent', false, codetext);

and replace with

if (tinyMCE.majorVersion >= "4") {
        			window.tinyMCE.execCommand('mceInsertContent', false, codetext);
    			} else {
				window.tinyMCE.execInstanceCommand('content', 'mceInsertContent', false, codetext);
			}

I use lasted version with wordpress 4.1 and found js error from difference verion of tinyMCE. Please fix it.
