Thread:Extension talk:WYSIWYG/Image copy/paste from word and clipboard doesnt work/reply (5)

Did you notice that you have to apply fix_of_empty_page_in_IE11 manually, because that file does not belong to wysiwyg extension. You also should have LocalSettings.php as is shown here: toolbar of WYSIWYG with WikiEditor. You should also check that your account Preferences=>Settings does not conflict, do not tick these: Show WikiTextEditor, Start with rich editor disabled, Open rich editor in a popup).

I have now fixed the backward compatibility issue with fix for corrupted category definition in #6 bundle based on Ricordisamoa's advice (extra_|_corrupts_category).

Strange thing if #6 bundle does not work in your environment, because I am using that bundle and it works without problems with IE11 and FireFox (v26.0, v27.0).
