Dear Friends,

Thanks to Rolf Turner, Brian Ripley and Patrick Burns for their  
answers.They don't quite resolve the problem, which I now realize is  
due to non-standard behavior of JGR, at least on my machine (I  
verified that Mac GUI works entirely as expected):

**** My installation********************
Running the JGR GUI:
 > sessionInfo()
R version 2.8.1 (2008-12-22)
i386-apple-darwin8.11.1

locale:
C/C/en_US/C/C/C

attached base packages:
[1] grid      stats     graphics  grDevices utils     datasets  methods
[8] base

other attached packages:
[1] JGR_1.6-2       iplots_1.1-2    JavaGD_0.5-2    rJava_0.6-1
[5] MASS_7.2-45     lattice_0.17-20

loaded via a namespace (and not attached):
[1] tools_2.8.1

********What happens with "?" and "??" **************

If I type "?normal" I get the long list, not "No documentation found."  
When I type "?plot" I get the help page for plot {JM}, and not  
plot.default {graphics}; when I type ?dnorm I get a rather long list  
of help pages.

If I type "??normal"
I get
?normal.htm
.com.symantec.APSock
.com.symantec.aptmp
.DM_1039:1232634821l:DlnIrq
.DM_11869:1232818209l:m4AGyL
.DM_13345:1232655220l:C1js39

.DM_16640:1232825979l:n5TrAz
.DM_18040:1232662823l:Gb81yX
…

******** Another JGR problem **************

Help pages for newly installed packages are accessible only after JGR  
is restarted.

Thanks,
MK
