ArcMap cannot be accessed after a Crystal Report is viewed, the report window is minimized, and the Crystal Report Wizard is reopened.
The report being viewed is in a modeless dialog box. This allows the user to minimize the report and restart the report wizard. Once reopened, the wizard is a modal dialog box, and the user is unable to access anything outside the dialog box.
Hold down Ctrl+Alt+Del to open the Task Manager.
On the Applications tab, click ArcMap.
Click End Task and close the Task Manager.
