gnome always hungs

[Wang Yajun <yalding ust hk>]

Hi:

I am using Debian Sid with Gnome 2.4.
The gnome panel always hungs.

It is caused by some window which lost responds.
Then whenever I lauch a program in top panel, the
panel lost responds too.
But all open windows are ok, I can switch
between them.

Anyone has some idea about my problem?
I am writing when the top panel hanging, :(

Thanks

regards,
yalding
