Gnome desktop freezes sometimes
I'm using Ubuntu 5.10 with Gnome and not too long ago I began having some problems.
Basically what happens is that when I open an application it freezes. The window opens, but there's nothing inside the window and I get a warning later:
"The window [windowname] is not responding. Forcing this application to quit will cause you to you lose unsaved changes."
If I don't do anything, the application quits by itself.
The icons on my desktop disappear sometimes, and this often happens right alongside Problem #1. They later reappear after a while, but it is quite annoying.
Does anyone know what I can do to fix these problems?
Thanks in advance.
