Hi,

first of all: Thanks a lot for the support. I do appreciate
that very much.

Well, it was meant to be a quick and dirty hack... And now,
it seems to be ugly, too, from a programmers point of view 8-S
But I'm not a programmer,... but you're right, common blocks
are thorn bushes... you have to cut deep and watch about the
place for a while afterwards...

: I would guess that the order of parameters in your common-block
: is incorrect, as the string you are getting looks like it's
: associated with a button or label widget, and you're passing
: this widget to CW_DEFROI().

Why is order so important? DRAW_Comm contains widget ids, that's
correct, but only of my DRAW widgets... So far there isn't any
common block for button widgets ;-)==) (one could change that,
of course... >:-)==)).

In the main program, the buttons are created with:

MenuDesc173 = [ $
{ CW_PDMENU_S, 1, 'FILE' }, $ ; 0
[...]
{ CW_PDMENU_S, 1, 'DISPLAY' }, $ ; 23
[...]
{ CW_PDMENU_S, 1, 'Display Mode' }, $ ; 26
{ CW_PDMENU_S, 0, '2D/Profiles' }, $ ; 27
{ CW_PDMENU_S, 0, '2D/Click' }, $ ; 28
{ CW_PDMENU_S, 0, '3D' }, $ ; 29
{ CW_PDMENU_S, 2, 'ROI' }, $ ; 30
[...]
]

PDMENU298 = CW_PDMENU( BASE241, MenuDesc173, /RETURN_FULL_NAME, $
UVALUE='TopPullDown')

Typical wided output that is (please don't cry 8-S).

Regards,

Peter.
