[ESS] I can not use install.packages

[Spencer Graves]

      What operating system do you use? 

      I use Windows, and I have had the same problem for years.  
However, I don't understand Emacs / Xemacs well enough to even consider 
fixing it,  Moreover, I suspect that virtually all of the ESS Gurus 
avoid Windows like the Black Death and are therefore largely ignorant of 
the problem. 

      My work-around is to use Rgui to "install.packages".  However, 
before using "install.packages" or "update.packages" in Rgui, I need to  
"q()" from Rterm in ESS.  Otherwise, if I I try to update a package that 
is currently "in use" under ESS, it deletes most but not all of the 
package and fails to install the replacement.  This "feature" of ESS 
would have me tearing my hair out if I only had hair left to tear. 

      Hope this helps.
