error loading source file

[Manning, Michael]

Hello Andrew

I have had exactly the same drama that you appear to be having.  I am
running pretty much exactly the same kind of system that you are (same
version of R, same version of ESS, however I am running a Win95 machine),
and am receiving the same kind of errors when I try to C-c C-l a source
file.  I have written help requests to the list a couple of times in the
past fortnight and have not received a reply, however I remain hopeful :).
I guess the bug is buried somewhere in ESS's lisp code. It is also beyond me
(for now :)) to find and debug the error.  I hope that this will be fixed in
the next release of ESS.  Otherwise, we will need to go back to running R
(and ESS) on machines with real operating systems...

Good luck
