Getting "object doesn't support this property or method" - doesn't make sense?

There could be two possibilities

The first time you excute  "obj = my_mapping.object()"

you get exact what you want, but in your "  // more code..." you manupulate screen so that 

1) "Click() " method is not available at that time  or



2)  another object appear, that could be return by " my_mapping.object()" in other words another object with same mapping has emerged by " // more code..."



I think most problably case 1 , if your abject take time to drow on screen
