>I done what you said but the debugger just sits on read events!

Then let's try starting the debugger earlier than that. Edit the form's BeforeOpenTables in the DataEnvironment. If there is no code there, put the following at the very top of that method

if .f.
   return
endif
dedefault()

In the debugger, break at location:

dataenvironment.BeforeOpenTables, 1

Now try running the form.
