I sort of found the culprit, but have no idea how or why it happened.

I have the following lines in my .Rprofile:

##.h <- taskCallbackManager()
##invisible(.h$add(function(expr, value, ok, visible) {
##  options(prompt=paste(getwd(),":",substring(date(),12,19), "> ",
##  return(TRUE)},
##       name="dateprompt"))

which, when uncommented, gives me the current working directory as well as
the time at the R prompt.  This seems to be what's causing my problem with
help under ESS.  When commented out, the problem dissappears.

Anyone have ideas how to fix this?  TIA!!
