synaptic and software updates don't work over VNC

[bsh]

Description: Ubuntu 8.04; Release: 8.04

Problem:
when I log in locally, on the computer, synaptic and software updates work just fine. however, I rarely do this, because I used to log in from an other PC, over a VNC connection, using Xvnc/vnc4server, viewer is UltraVNCviewer on XP.
when using synaptic or the software updater this way, they do not work.
In Synaptic, it just displays the progress bar after it's loaded, checks for the available programmes, but the progress bar never reaches the end and it never gets to display the list of programs. when I check for updates, the software updater displays a progress bar and "building dependency tree" (or something like that, the language is hungarian), and the progress bar never finishes. I have tried to change the sources, it started to download the list files, but after 30 mins it didn't finish and many of the files were "unsuccessful". also tried different sources (while logged in locally), the servers didn't have any updates etc., but the main server had 69 or so... something must be broken in the updates distribution...?
apt-get still works fine over vnc in a terminal, and over ssh login too.
all in all: synaptic & co. doesn't seem to work over vnc, but they work fine on local login.

notes:
* this is not a "clean" install, i have installed 7.04 from a live cd, then applied all the available updates, the upgraded to 7.10, then upgraded to 8.04. vnc was working fine on 7.04 and 7.10.
** this is the default 7.04 desktop i386 with gnome, but i use xfce instead of gnome by default. but strictly speaking this is not a "xubuntu" install, it's just normal ubuntu with xfce installed.

hope this information is enough...

Hello,
It's the same here.
xubuntu 8.04, updated from xubuntu 7.10.
I use vnc4server (last version: 4.1.1+xorg1.0.2-0ubuntu7).

I can add that the progress bar is updated and reach the end if I continue to change focus between the update-manager window (or the synaptic window it 'doeasn't matter) and another windows (or the desktop).

Hope this helps.
If you need more information just ask :)

Bye Jack

I am changing the package from synaptic to vnc4, which appears to be the cause of the failure.
