Debugger not working in Toad

Hi,

Even though this forum is of Oracle, I thought I will post a question related to Toad here since this is indeed a PL/SQL related question and I know lot of us have been using this tool for a long time.  I apologize if this question is found to be out of place here.

I have compiled the sample stored procedure that was given in the toad tutorial for debugging purposes.  I used the compile with debug option.  Created some watch variables and put some break points.

When I run the procedure from the editor using Execute with Debugger option, the parameter window shows up.  I enter the parameter value and hit execute, but the debugger just completes execution without stopping at any of my break points.
