SAOImage DS9 Known Issues
Windows Vista
Vista has new restrictions on who can write into the Program Files
folder, which is exactly what DS9 wants to do. Please install DS9 as
the Administrator, or install after changing the security level of the
Program Files folder. For more information please click here.
Linux GNOME and KDE
An issue concerning Linux GNOME and KDE, animated cursors and X windows
resources has come to our attention. There is a bug within the X11
server in which memory is not freed properly if your window manager
uses animated cursors (the watch / hour glass cursor for example). In
this case, a small amount of memory is allocated and not freed each
time DS9 changes the cursor to indicate that it is busy. While the
amount of memory is quite small, it can accumulate over time. For
example, if you where to pan, zoom, and rotate an image over 200 times,
the amount of memory involved becomes quite large and can lead to
instability with the X windows server.
The work-around involves setting the X windows resources database to
enforce the use of standard, non animated cursors:
$ xrdb -merge
Xcursor.theme_core: false
Xcursor.core: true
<cntrl-D>
or set these resources in your .Xresources or .Xdefaults file.
Darwin
Darwin requires the use of X11
for MacOSX 10.4 or higher. For information on using SAOImage
DS9 with IRAF under MacOSX, please see The Macintosh IRAF

Plot
There is a know bug with Plots and the Zoom function. Bring up
an analysis plot. Click left button to start the zoom function. Without
completing zoom (by clicking a button), go to FileClose.
Resulting error message will appear: An internal error has been
detected: invalid command line:".atmenu122g" menu and choose.
In certain cases when the data contains x errorbars, and there values
are quite large, compared to the data itself, and if displayed with
errorbar style 2, the rendering may become corrupted. In this case,
only use style 1.
IRAF
DS9 now supports IRAF's new IIS image display protocol. However, there
is
one minor problem with the mscred task msczero. Before
using msczero, issue the following command in the cl:
cl> set disable_wcs_maps=""
cl> flpr
