blender 2.59 process doesn't close upon exit

Hi,

I’m trying to use blender 2.59 but I’d like to resolve the problem I’m experiencing before getting into learning blender further.

The problem is that when I close blender via File>Quit, its process does not end & I can still see it using ‘top’ and it is eating up 100% CPU. My system is dual core so it isn’t causing my system much of a problem but I’d like to fix it. If I run blender by double-clicking its icon I have to kill it manually via the command line. I have now just started blender via the command line to see if there were any useful messages & found the following information:

zippy@debian:~/special/other/blender/blender-2.59-linux-glibc27-i686$ ./blender
ndof: dead zone set to 0.10
connect failed: No such file or directory
ndof: spacenavd not found
AL lib: pulseaudio.c:612: Context did not connect: Connection refused

^C
zippy@debian:~/special/other/blender/blender-2.59-linux-glibc27-i686$

I am able to stop the process simply by Ctrl+C from here.

My system is 32-bit Debian 6 Squeeze with all security updates etc. My system is 2.4Ghz with 4Gb RAM, ATi graphics using fglrx. Has anyone else got this problem & is it fixable?

Thanks.
