A Response Window is the PowerBuilder's equivalent of a Windows dialog box; it is used to accept response from the user, to display warnings and so on. A response window demands action from the user and once active remains active until the user answers.
If a window behaves in this manner it is said to be modal.
When a response window is opened, you neither can move to another window within the same application nor can you resize, minimize or maximize the opened response window. You can switch to any other application that you have opened under Windows, but when you return to the current application, the response window will still be active.
A typical example of where you might encounter this type of window is when you want to save a new document using your favorite word-processor. When you click on the save option, the word-processor can't save the file as the document is as still untitled and therefore displays a 'Save As' window, asking for the required information.
Until you answer this question, the word processor will not allow you to continue, unless you click on the Cancel button and throw away the whole idea of saving the document.
