how to know what code are calculating??

[leanpilar]

I have a problem with one form that some field become not editable and I want to find what code are doing...
I clear 1 of my code on current of one subform and all code on load but after 1 sec my mainform and my subform become non editable
in intermediate window

 ?Forms!mainform.allowedits 
True

result as true but after I run code

Forms!mainform.allowedits = True

I can edit everything.
On open I can see on red button bar loading.. and calculanting and when it stop it become blocked...
is there a way to see what code are running??
