In fact I did not, and now it works fine, indeed.  I should have thought 
about this... sorry!

This works very well now, and I would even recommend that this should be 
implemented in the next distributed package should it not introduce 
problems, since I find it really useful for dealing with the temporary 
files.
Thank you so much for such useful advice!
