4.0	Release Notes
------------------------------------------

1.  When setting the background color on a grayscale MrSID (*.sid) image, a shade 
of gray must be used.  

2. When viewing a grayscale MrSID image a flash of a color besides a shade of gray may appear (i.e. blue or green). In this instance, select View Properties from the View menu and the View Properties dialog will appear.  Click on the Set Default button until the Background Color box turns black.  Click OK and the problem should disappear.

3.  CMYK images are displayed with a default unit of meters. 

4.  If a MrSID (*.sid) image is zoomed repeatedly before the image is fully loaded
there may be unexpected behavior in the redraw of the individual zoom level.

5.  Upon canceling a print job a partial print of the image will still be generated.

6.  If a corrupted file is opened in the GeoViewer, an error message stating "Marker Problem Encountered.  Possible File Corruption" may appear. This error message may result in an inability to open other images.  If this occurs shut down the GeoViewer via the CTRL+ALT+Delete buttons and restart the GeoViewer.

7.  Windows 95 users:  If you receive the following error after installing the
MrSID GeoViewer 2.1 and restarting the computer:  Error Message:  Error Starting 
Comctl32.dll.  

To correct this problem You need to replace the comcat.dll file on your system in order to use the MrSID GeoViewer. Visit the Microsoft Knowledge Base article number Q180071
at <http://support.microsoft.com/support/kb/articles/Q180/0/71.ASP> and
download the Msvbvm50.exe file linked to from that article. Run that
application to replace the DLL, and relaunch the GeoViewer.

8.  Windows NT Server users:  Windows NT Service Pack 5 is required.
