 Windows are grouped by tags. Each window can be tagged with one or multiple
 tags. Selecting certain tags displays all windows with these tags.

-dwm contains a small status bar which displays all available tags, the mode,

+dwm contains a small status bar which displays all available tags, the layout,

+floating window is indicated with an empty square and a maximized
+floating window is indicated with a filled square before the windows

 .SH CUSTOMIZATION
 dwm is customized by creating a custom config.h and (re)compiling the source
 code. This keeps it fast, secure and simple.
-.SH CAVEATS
-The status bar may display
-.BR "broken pipe"
-when dwm has been started by
-.BR xdm (1),
-because it closes standard output before executing dwm.
 .SH SEE ALSO
 .BR dmenu (1)
+.SH BUGS
+The status bar may display
+.BR "EOF"
+when dwm has been started by an X session manager like
+.BR xdm (1),
+because those close standard output before executing dwm.
+.P
+Java applications which use the XToolkit/XAWT backend may draw grey windows
+only. The XToolkit/XAWT backend breaks ICCCM-compliance in recent JDK 1.5 and early
+JDK 1.6 versions, because it assumes a reparenting window manager. As a workaround
+you can use JDK 1.4 (which doesn't contain the XToolkit/XAWT backend) or you
+can set the following environment variable (to use the older Motif
+backend instead):
+.BR AWT_TOOLKIT=MToolkit .
+.P
+Recent GTK 2.10.9+ versions contain a broken
+.BR Save\-As
+file dialog implementation,
+which requests to reconfigure its window size in an endless loop. However, its
+window is still respondable during this state, so you can simply ignore the flicker
+until a new GTK version appears, which will fix this bug, approximately
+GTK 2.10.12+ versions.
