Cannot stepping through VB code

[Razak]

Hi

I made a function in global code to be executed when ever the file is
opened. I made a macro by the name AutoExec, put an entry with action
RunCode and the function name as the parameter.

In the function code, I place a breakpoint at the first executable line. The
problem is, the debugger does not break at the line. If single-stepping by
pressing F8, the code will be executed as normal.

Is there any settings to enable debugging through code?

I'm using Access 2003.

Thanks
