   There are three "modes" that widgets take on when you're modifying them
with the Control Panel Editor ( whether its from DataScribe, Module Builder,
or Module Groups in the Map editor ).  They are something like the following :

   * UNSELECTED - the widget's title ( provided it has one ) is gray, and the
	widget isn't outlined in black.  In this mode, the widget is not
	modifiable.

   * OUTLINED IN BLACK, with title grayed out - in this mode, you can 
	interactively move the widget ( by grabbing the widget anywhere inside
	the black outline except the lower right hand corner ), or resize the
	widget ( by grabbing in the lower right hand corner of the outline ).
	This mode is obtained by clicking the pointer over the widget.

   * OULINED IN BLACK, with title also in black - in this mode, you can 
	change the limits for dials and sliders, or the widgets default
	vaule.  If you double click over the widgets labels ( numbers )
	the text entry field should turn inverted ( black background, 
	blue numbers given a default configuration ), at which point, you
	can enter in any new value.  Press ENTER to make the value stick.

   Hope that helps.

Thanx,
Dave

I have been unable to get mbuilder widget limits to 'stick', and have been 
using the following procedure instead (even thought the manual says it 
'can't be done'):
      in your code, ad:
          #include<cx/UserFuncs.h>
          void wdgt_init()
          {
               /* an example */
               cxInWdgtDblMinMaxSet("Magnify",2.0,10.0);
          }
          cxHookTable cx_HookTable[] = {
               { cx_func_init, wdgt_init},
               { cx_func_last }
          };

      to compile:
          make clean
          make all    (and note exactly what commands are used)
          edit 'modulename'.mdw.c to remove its cxHookTable def
          execute by hand the makefile commands following the message
              '...creating module wrapper...'

This causes the widget's min and max settings to be set when the module is 
loaded into the map.
