System information

Hi

You can move a Modal WebForm so that the webform including top bar (containing close icon) goes outside of bottom part of screen. In such condition you can neither close Modal form nor close the parent webform.
Please don't allow top bar of modal Webform go out of screen as in gambas QT forms.
