Question:Why calling object method in debugger fail?

Is there a workaround to being able to call object method inside the debugger? I use Objects everywhere and hard to debug things when not able to try calls inside the debugger.

Here is an example.

This worksheet below has the code to reproduce this. Ofcourse the code works when I run it in the debugger using "continue" button, or using the "next" or "step". But I need sometimes to check something before doing this.

"me"
