Hi Bernard
I wasn't able to repro your problem until I put a call to PPG.Refresh into my OnInit.
And if I call PPG.Refresh from an OnChanged callback, then my custom command in global scope is triggered again.
I would think of it this way: PPG.Refresh is going to reparse your plugin code, and so your global code is going to be executed again. I didn't look into the code to see what actually happens, but it looks like that is what happens.

Stephen: yes, I call PPG.Refresh() in a custom function. This is the only place where I call it. So the Refresh() call, even if done in a function scope, takes place in the global scope?
Btw, the function that calls Refresh, is called in many circumpstances (like if the user edits a text field), and when it is called, I see the custom command defined in the global scope is not called.
Guy: The reason is that the parameters are added in the Define callback, while the layout is built in a custom function. Few of these parameters are control combos.
To populate these combos with items, I call a custom command that lists the directories in a specific location. Since I never know in advance what directories will be there, I want to set the default value of the parameters with the first item in the list, and use the same list to build the control combo itself. Also, the function that populates the layout may be called several times during the PPG inspection. I would avoid calling the same commands over and over.
Threfore, I felt logical to do this process only in one place, in the global scope.
