Inserting an orientation icon into a specific viewport displays it in all viewports regardless of the "Show in Current View Port Only" setting. For example, consider the following scenario:
1. In a produciton drawing, the user has launched the "Orientation Icon" command (SCASSORIENT);
2. The user has selected a viewport to insert the orientation icon to.
3. In the "2D/3D Orientation Icon" dialog, the user has checked the "Show in Current View Port Only" setting.
4. The user has finished the command.
If the user does Zoom-Extent in other viewports, the user will see that the orientation icon is visible in all viewports. In the correct situation, the orientation icon should only be visible in the viewport where it was originally inserted to.
