I believe there is also a dependency towards 'reposTools'
(although no version number is specified).
Which version do you use ?

It looks like a silly bug in the 'autodownload' mecanism (one more). I'll look at that.

This is annoying, but fairly out of the control of developpers of the affy pack.

The mecanism involved is an attempt to free people from the trouble of taking

Win XP ? ;) ). Thanks for the report.
