Display Issues                                           

Where did the CIS Control Panel go?  I can't access it, but the feedback window is open and waiting and I can see the CIS Suite running on the Windows taskbar.
Sometimes the windows to control the CIS Suites are positioned off of the viewable area, particularly after changing desktop resolutions or monitor layout.  The positions of the CIS windows and panels can be reset to the top left of the primary screen.

To immediately reset the windows' positions for the CIS Suite being used:
1)  Left-click on the CIS icon by the clock in the system tray.
2)  Select  Help  |  Reset CIS windows positionsows to the top-left corner".

The CIS Suites run very slow but the computer has a fast CPU.  Why??
Be sure the feedback window is positioned on one monitor only.
Check to see if the computer is using an Intel graphics chip.  It it is, please read this.

Lots of time the imagery flickers in weird ways.  What's going on?
1)  It could be a problem with the graphics drivers.  Try updating the graphics drivers.
2)  If updating drivers doesn't help, try switching to a different graphics renderer.
      (change Contact's settings via the "Help" menu, or use the CIS Display Preferences utility).
If it continues to happen, please read this.

Intel graphics chip issues
Intel has an extremely poor track record supporting 3D graphics.  Intel GPUs and drivers are frequently not sufficient for use by 3D applications.  Read more here.
