By default, the module respects the caller's `dialog_size` option. If
you want to set dialog boxes maximized by default, you need to:

1.  Go to *Settings -\> Technical -\> Parameters -\> System Parameters*

2.  Add a new record with the text *web_dialog_size.default_maximize* in  
    the *Key* field and the text *True* in the *Value* field
