Me too!
Same problem here. It helps sometimes not to change the label's size. I
use a monospaced font and initialize my labels with something like
VALUE=' ', and don't change the number of
characters later.
Similar problem: try adding another base to the bottom of your widget.
Again, the whole widget is resized. Not always, but often enough. Even
labels become bigger in both X and Y direction.

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.
