My questions are; Is there a package that installs all the MUI libraries.
Yes, I maintain a MUI archive which contains current versions of MUI custom classes. Download it from here:
http://amiga.serveftp.net/downloads.htmlThere are new versions of TextEditor and a few other custom classes which have just been released, but I've not yet added these to the archive. The previous few releases of TextEditor had introduced some nasty problems, but the classes in the current MUI archive are known to work OK. Will add them once I've checked they work OK with YAM, etc.
