My orginial intent in using the XSIZE and/or YSIZE keywords in WIDGET_LABEL
was to create a fixed size label where I could write various things while
the widget was running. The key word idea here is fixed size. I did not
want my widget geometry shifting around after every WIDGET_CONTROL call.
As it turns out it may have been unneccessary. As it is now I'd have to
agree with you.

Yes! Text widgets update much slower, and the XSIZE and YSIZE keywords
to WIDGET_LABEL are in pixel units. I personally think these should be
in character units, since that's what you're displaying! It's a shame
that you have to upgrade your code as well!

I actually have this problem under 3.6.1c. It was much better in version
3.5.1. The only workaround I could come up with was to update the label every
10th step instead of every step.
It's really annoying.

I also ran into this problem during the beta testing of IDL 4.0, and complained
to RSI. They said that widget_label is now working corectly, that it's
supposed to be in pixels. After some experimentation, I came to the conclusion
that previous versions of IDL were ignoring the XSIZE and YSIZE keywords and
simply sizing it based on the number of characters. We were only being fooled
that the XSIZE and YSIZE keywords were doing something.
To solve this problem, we've gone through our code and removed all references
to XSIZE and YSIZE in calls to WIDGET_LABEL. In my opinion, having XSIZE and
YSIZE in pixels for a text label is useless.

Your problems are shared by many, I think. We were speaking of these
type of problems earlier in the thread 'widget convulsions'. I can verify
that I have these exact same problems as you now that we've upgraded to
4.0. We are on a HPUX / X11 system.

... the rest deleted.
Looking at things a bit more, I notice that one of my widgets is running
much slower (a factor of 2 or more) and is now flickering. I traced this
"problem" to a point in the program where I am plotting calculations on the
fly and displaying some updated information in a WIDGET_TEXT field. It
appears that the formerly smooth operation of the following line under IDL
V3.6.1 has been changed in some way under V4.0.
widget_control,wids(2),set_value=curtim
For some reason, updating the value of a WIDGET_TEXT of a realized widget
now consumes enormous resources (It takes as much time to update the field
as it does to perform the complex orbital caclulations I am doing) and in
the process also causes my widget to flicker now. This is most annoying
and unacceptable.
Based on this and what I have read in this group, I reccommend that current
users do not upgrade to V4.0
OH BTW, I have gotten wind of a new maintanence policy from the folks at
RSI. In addition to a price hike, they are now charging floating network
sites for each and every license in the site (they used to charge by the
site). So, for a 6 license site running under OSF the annual maintanence
has gone from $250 to $2250 ($375 * 6) per year. So plan your budgets
accordingly.
Time to look again at that site license from PV WAVE. Since I have
to rewrite that code anyway to work under IDL V4.0, I might as well
consider my alternatives.
