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).

With IE11 I have not noticed before that I have on page "Tools=>Compatibility View settings" selected option "Display intranet sites in compatibility view". With this setting on (#6 bundle) wysiwyg works ok with IE11. If I deselect that setting in IE11, wysiwyg editor won't start and it reverts to wikieditor.
