When a browser is used as in an instance of an item, it creates a button and this can be used within the boundary of ceiling-dir or at most to the workarea. It can not go beyond it.Now, when we use Callout as a subelement of browser, it calls an external program. This is outside the workarea. Is not this violation of the bowser limit that it can not go outside the workarea ? Will it create two buttons (one for browser and one for callout) ?why would one like to use callout with browser ?Thanks
