Does MUI4 really do the necessary MUIM_Hide -> MUIM_Cleanup -> MUIM_Setup -> MUIM_Show cycle each time a config value has changed?

I just ask because each instance of TE.mcc will update its configuration in MUIM_Setup only and MUIM_Setup must be issued only once according to MUI's documentation.

@all
Anyway, TE.mcc 15.34 has just been released. The main focus was the possible memory trashing while editing some text. The Undo/Redo handling and the configuration change should be unrelated. However, everybody who encountered this issue please check again with the latest version. If the issue is still valid, then please report it at TextEditor.mcc's bug tracker. This makes it much easier for us instead of having to wade through lots of fora.
