BUGS in DEGUI 1.21b

Example #4 (ex4.cc) didn't call the get_text function to get the modified
text out of the edittext_object.  That resulted in the example always showing 
the unmodified text at program exit.  The object is OK, but the example was
wrong.  It's been fixed in this version.

Fixed a problem where the listbox would not always show the last entry in the
list. 


BUGS in DEGUI 1.2b

Using the default behaviour in a click callback for a list object causes a 
page fault.  In fact any callback that called default_behaviour that calls
a msg_xxx function that used send_message(MSG_xxx) will cause a page fault.
This is because the object_message_proc cannot be entered more than once 
per message because the default_object is set to NULL on exit of 
object_message_proc and when the first message returns, any use of the 
default object i.e. to check flags will cause a page fault.

Workaround:  Don't use click callbacks, better to use derived objects....
