After installing the BOINC manager, and launching it,
it immediately hangs and displays only a empty white window. The computer is a windows xp sp2 machine,
2.6 GHz Intel CPU, 1 GB RAM. I have tried redoing the install, rebooting etc, but it does not help. I am behind a rather catchy firewall, but if the problem is only a matter of communications, I think the program should tell me, rather than hang forever.

Uhm, ever thought of looking in the forum if your problem was handled yet?
Like this thread?

Yes, I did, and as my post clearly states, it did not solve the problem !

If the firewall will not allow traffic between the daemon and the manager it could cause the behavior you are seeing.

boinc.exe needs internet access on ports 80 and 443, local access on ports 1043 and 31416.
boincmgr.exe, boinccmd.exe and boinc.scr need local access on ports 1043 and 31416.

I have found that I can partly workaround the problem by first starting the boinc.exe "daemon" manually, i.e. by dubbelclicking it and keep it running in a command window, and then start the manager. Then, and only then, the manager seems to run correctly, and it gets some work done. But the boinc.exe won't
start the "normal" way, which I guess is by beeing started up by the manager
when I start it.
Does this give anyone a clue as to what the problem might be ?

I am not all that familiar with firewalls, but I do know that the firewall
in question is an "external" one, ie, there is no firewall software running
in my local machine. Can an external firewall really interfere with the communications between local applications ? I have no possibility to open up
ports in the firewall in question, so if that is the case, then I can't do anything about it.

Sounds like the normal port for daemon to manager communications is being blocked. M$ sits on it with some of their programs. Starting the daemon first will usually get around this, starting the manager manually after the boot process is finished also helps sometimes.

So, I have uninstalled and reinstalled it, and selected the "run as a service"
option at installation, and this makes it work. Altough I loose the screensaver.

Not if you don't want it to.
