FLTK menus not drawn until mouse movement

[wombat]

Several applications that use FLTK -appear-to-be- broken since the upgrade from ubuntu 10.04 to 10.10.
(specifically VMD and "FLTK Sudoku")

These applications have menus which usually (but strangely not always) fail to draw the pull-down list-of-choices, when you click on them. Oddly, if you pull down anyway, then the list of choices is drawn, but only if you move the mouse downwards after clicking.

So far, I'm noticing this in the molecular visualisation program "VMD" and fltk games like "FLTK Sudoku". (You can test the problem quickly by installing fltk1.1-games.) I don't know if this was happening earlier, but I did not notice it until after the upgrade.

I noticed this on two different computers which were recently upgraded to ubuntu 10.10, with different hardware. (One has an old nvidia graphics card. The other has a new ATI card. Both use proprietary graphics drivers. I'm happy to provide graphics driver versions, if somebody can tell me how to determine this.)

I forgot to mention that I'm using the GNOME version of ubuntu (gnome desktop 2.32.0).
(I've no idea if this is relevant.)

In what way is it related to FlightGear-Atlas ?

[Knut (knut-redhat-bugs)]

No it is a bug in fltk package.

This appears to be effecting Fedora users as well

According to this post,
http://www.ks.uiuc.edu/Research/vmd/mailing_list/vmd-l/16727.html
fltk menu'ing seems to work, albiet a little differently that expected.

I'll try to confirm when I get a chance.

[Fedora (fedora-redhat-bugs)]

This message is a notice that Fedora 14 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 14. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 14 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
