Version 3.52
* Fixed bug where if you went into full-screen mode, and then right-clicked for the context menu, and selected "All menus", MUSHclient would crash or go into a loop.
* Added "Edit..." buttons to some configuration dialogs, such as the Notes screen, and editing macros.
* Added support for the Lua scripting language, see the forum topic for more details:
