[R] Memory leakage?

Dear Prof. Ripley:

Thank you for your suggestions!

I haven't tried re-installing windows yet, because it seems to be a big task 
for me and also I kind of doubt that the problem is due to my own 
computer(s), because the same problem happens to 3 different computers: one 
Dell desktop in school runing Win2K and R 1.6.1, my Dell laptop runing Win 
XP Professional Edition and R 1.7.0 and my new Dell desktop at home (just 
bought less than a month and only a few basic softwares were installed) 
runing Win XP Home Edition and R1.7.0.  (may be they're all from Dell :-)) 
I'm still looking for the pattern of when this happens, but so far, it seems 
to be random.

I always use Rgui in SDI mode (under XP) and it always shuts down
completely for me.

There was only one release of R 1.6.2. This not what is meant by `memory
leakage': that is when an application allocates memory and does not free
it: it goes away when the application is exit-ed.

I believe the problem is with your own computer (or how you use it,
including other software you may have installed): have you tried
re-installing Windows?
