When we execute a report from the 'designer' it works fine. When executed through the 'Printer', just after the range selection (without any selection) when presses 'ESC', windows throws a message as illegal operation. In some of the start-lists the system shows as if printing and the computer gets freezed in the QR-designer screen it self.
Using QR 6.1F presently, but ordered the latest upgrade recently. Yet to be installed.
