Solution or Workaround
Doing an Edit | Copy Visible Page, and then pasting that page into Microsoft PowerPoint, additional agis32.exe processes show up in the Task Manager, and the system CPU is at 100%.
Windows NT thinks there are still Atlas 4.0 processes running, even if they are finished drawing.
Manually remove the agis32.exe process in the Task Manager by selecting it and then clicking End Process, click Yes when prompted. This will remove the process and bring your CPU back to normal.
To prevent this, copy the page to the clipboard and bring it into PowerPoint from the clipboard. You will not see additional processes in the Task Manager.
