WOOHOO! That did it! Inserting the UPDATE in the following code fixed the problem.
You're a star! This problem was annoying the crap outta me to the point of tossing and
turning at night.
Onya!

Well, well, well. Isn't that the old
IDL-5.0-or-which-version-was-it-widget-growing-bug, probably related to
http://www.dfanning.com/idl5_info/tlb_resize_problem.html ? Which,
according to RSI, was a bug, and they wanted to fix it really soon?
Which they never did? At least I never heard of that.
WIDGET_CONTROL, UPDATE=0/1 seems to do the trick, at least in most
cases.
PS: Could you do a WIDGET_CONTROL, Netscape_ComposeWindow, XSIZE=72?
This makes your posting easier / less horrible to read for people with
news clients set to 80 characters per line, and I could quote your text
without enlarging my composing window.

As I understood you modify an already realized widget.
I had similar experience, even without grid layout bases some time ago.
What helped me was using:
widget_control,tlb,UPDATE=0 (1)
before (after) the modification.
Thisway the sizes were correct and the speed the changes were
carried out was drastically higher.
Hope that helps,
marc

Thanks,
I have to pass the compliment to Stein Vidar Hagfors Haugan,
actually I think I got it long time ago from Davids page Alex
mentioned below (but didn't remeber from where I had it).
Anyway, good that it helped you!
But was astonishes me is, that you use the update BEFORE
the base is realized.
I didn't know that update makes a difference then.
What I do not understand in your program is,
why you first unmap the base during creation
and then map it when realizing?
Until a base is realized (= brough to screen) mapping didn't matter
(at least for the tlb).
OR: Might it be that in the real program the realizing is done before
and
so the realizing there is unnecessary (which would also explain the
astonishing effect of update to non realized widgets)?

Hmm, I don't know about that. I'm not resizing the tlb interactively. But who
knows? might be.

Yes that worked (see previous reply to Marc Schellens)

72?? What are you - an IDL or a fortran-77 programmer? :o))

While I think you should get a different news reader, I'll compromise at
XSIZE=80. :o)
