On your right mouse menu. Phishing and hacking sites have made doing Cut-Copy-Paste with JavaScript a security risk. Explorer requires responding to a security alert, and FireFox has simply disabled Cut-Copy-Paste through JavaScript (this week anyhow). Since eZwysiwyg does not make use of a proprietary right mouse menu, Cut-Copy-Paste is where they've always been, on your right mouse menu.

Editblocks, Includeblocks and Excludeblocks prepared for ContentEditable and EditWrx will work in eZwysiwyg in spite of the fact that they use attributes and eZwysiwyg uses class names. However, Login Prompts on pages will continue to point to the other program instead of eZwysiwyg. You can easily fix that by renaming the eZwysiwyg folder and file to match the url in those Login Prompt src values. For example, if your Login Prompt src url is "/editwrx/wrx.cgi", then rename the default eZwysiwyg /"editor" folder to "/editwrx" and rename the default eZwysiwyg "edit.cgi" to "wrx.cgi".
