Not on my computer.

I get TRUE twice whether at start up, source()ing .Rprofile, or C-c C-n'ing the lines from emacs ESS.

I have to type

         load(".RData")

_after_ startup to get behavior like you describe.

Perhaps, you have something later in your .Rprofile that specifically load()'s your old .RData?
