Thank you. Try these newer binaries: https://sourceforge.net/projects/wxlua/files/wxlua/2.8.12.0/ Personally, I don't use update ui events as they are sent a little too often for my likes. I find that a single function that updates the gui state, menus, toolbars, buttons, etc.. works very well and is less cpu intensive. All you have to do is call it whenever there is a chance the state will change. This also has the benefit of getting all the update code in one place since the state of various items are often interrelated. Regards, John
