[R] Memory leakage?

[Tao Shi]

Hi, all:

I'm using R 1.7.0 on WinXP under SDI mode.  However, very often after I 
closed all R windows, my CPU usage was still 100%.  By checking the task 
manager, I found there are one or several "Rgui.exe" still running and took 
all the CPU.  I had to close them one by one manually.  This happened to me 
with R 1.6.1, R 1.6.2 also and also on Win2K.  Rememeber there was a "memory 
leakage" problem with the early release of 1.6.2.  Is this what I'm 
exprencing here?  Or this is due to I'm runing R under SDI mode, b/c my 
colleague hasn't found the problem with his R 1.7.0 or other versions which 
are runing under MDI mode.  Help............
