R help - Nov 2003 - Hidden Rhistory files

Hi all,
I've ecountered a problem in the last few days with my .Rhistory file
not being able to be updated when I quit an R session because its file
attributes under Windows have been set as "Hidden". Recently, I put
the
following line in my global Rprofile file:-

history(max.show=Inf)

so that I automatically open the entire history file for a project when
I begin a session, but I don't see why that would cause a problem.

This problem has arisen several times in the last few days while working
on different Rdata files in different folders. When I manually uncheck
the "hidden" attribute of my Rhistory file, the problem goes away. But
why did the files get that attribute in the first place? Is this
something that R itself may have done? I'm running R Version 1.8.0
(2003-10-08) under WinXP.
Cheers, Duncan

It's nothing to do with R: there is no code looking at file attributes in R.

Perhaps you have set your OS to mark .* files as hidden somehow?
It does not happen for me or any of our users on XP.
