Jean-Yves -
This is definitely a bug in IDL 5.0. You can work around this problem
for now by using:
widget_control, base, update=0
widget_control, label, set_value='I have moved'
widget_control, base, update=1
RSI has confirmed that this is indeed a problem. Our programs would
resize themselves so that the buttons, sliders etc. would be off the
screen! You might want to check David Fanning's web page to look for
a pretty comprehensive list of bug reports and their replies.
