If your program reads the floating point numbers in the format <tt>123.45</tt>
from a file, it may suddently start returning just <tt>123</tt> instead of the
future, probably as a separate library.

+It seems that some versions of RedHat include a badly patched version of GTK+ (not wxGTK)
+which causes some trouble with wxWidgets' socket code. Common symptoms are that when
a client tries to establish a connection to an existing server which refuses the request,
the client will get notified twice, first getting a LOST event and then a CONNECT event.
This problem can be solved by updating GTK with an official distribution of the library.
on a 2.1.X system. It will then run on practically all
Linux distros (if you link you app statically against
the image libraries and std C++ lib)."

+
+<h3><a name="#static">Can I statically link the GTK+ library?</a></h3>
+
+No, this is not possible. It leads to crashes in GTK+.
+<P>
+
+<h3><a name="#charinframe">Why does my simple program using
+<tt>EVT_CHAR</tt> not work?</a></h3>
+
+In wxGTK, the frames never get focus and so can never receive <tt>CHAR</tt>
+nor <tt>KEY</tt> events so an <tt>EVT_CHAR</tt> handler for a frame will be
+never called. To receive these events, you should create a <tt>wxPanel</tt>
+inside the frame and register the key event handlers for the panel, not the
+frame.
+
+<p>
+
+<h3><a name="#debugging">How do I trace the cause of an X11 error such as BadMatch?</h3>
+
+When a fatal X11 error occurs, the application quits with no stack trace.
+To find out where the problem is, put a breakpoint on g_log (<tt>b g_log</tt>
+in gdb).
