30 Apr 2000, eval1127@eng -- unfortunately, contrary to the previous evaluation (under kestrel-rc2), this problem DOES appear to exist,
even in kestrel-rc3 and 1.3.0-C (on both win32 and Solaris). I'm not sure how I managed to make it work. (Perhaps I slightly
permuted the order of steps-to-reproduce).

Anyway, this IS, unfortunately, a bug. (see also 4131008, 4134077)

15 Mar 2000, eval1127@eng -- a validate/revalidate after the title change works fine (at least on kestrel-rc2).

The size of an iconified JInternalFrame isn't being set based on the current
title text. It appears to be set once, the very first time the frame is
iconified. This is very inefficient, wasting a lot of space, for the cases where
the title text gets changed during the course of a session(like in my app).

The following test app can be used to see the problem. After invoking iconify
both internal frames. This will set the width of the iconified "bar". Now open
the one with the longer title and click anywhere on the interior of the frame to
open an input dialog. Change the title text to be something really short, like
"Hi". Now minimize the frame again. Notice how the iconified "bar" is still
really wide, when it _should_ have been resized to match the title text?

4/19/2000 user notes (and apparently had previously, in earlier mail) that the workaround
does NOT work for him, even with 1.3 RC3. It worked fine here on a uniprocessor
machine (user has only multi-processor machines).
