Actually it does not have to be. But I thought that anything called from the windows with the property ShowWindow - 2 Top, has to be modal. My mistake.

>>Antonio,
>>What you wrote makes sense. But there is one problem. The main form calls a modal form and that modal forms creates a report (in a preview mode). So, if I do not have the _screen and only the main form, the report preview will only be shown within the size of the main window/form. Therefore, in order to be able to view the report in full screen (in a preview mode), I had to go with the _screen.
