MmaTranslator:-MmaToMaple unable to read files

[Peter Pein]

Hi,

I wanted to use the maplet MmaToMaple to convert a (very) small Mma
notebook to Maple syntax. I created a .nb-file with a slightly crippled
version of the function (deleted option Method->"AlternatingSigns" and
precision related stuff from the original function). This file - df.nb -
resides on the (Windows7-) desktop. File properties are normal (full
access).

Entering
> with(MmaTranslator);
> MmaToMaple();
opens the maplet and I use the "Browse..." button to find and select
df.nb. Maple opens an error window,telling me "Unable to import" in the
title bar and "permission denied: no read access
(C:\Users\Peter\Desktop\df.nb)" in the window itself.

Using sysinternal's process explorer, I verified that mserver.exe runs
as user \\Leierkasten-II\Peter. Trying several other locations for the
file (including an external drive) results in the same message (modulo
path to file).

A Google search for 'Maple MmaTranslator "no read access"' gives no results.

Meanwhile in Berlin: ;)

I did the conversion by hand and it works almost as expected, but I'd
like to know where I went wrong.

Thanks in advance,
Peter
