I dropped clistobj on my form. Then I right-click, choose Edit from the list. Right-click again and choose Builder. But I am getting "Invalid subscript reference" error in the code STORE EVAL(This.cObjectProperty)TO This.iControlSource. If I click OK, it goes to MM Builder window. But I am not sure of the cause and effect of this error.
Be sure that you're in the project directory and that you've executed startmm.prg
If you're running multiple project on your machine you may have to delete all you're fxp's from Mere Mortal Directory. When you execute startmm it'll recompile all the files for you.
