Dear Gretl Developers,
A colleague here at my work is trying to perform some regressions
using .xlsx files but he is getting the following error messages:
"Invalid argument for function" in the GUI
"gretl_unzip_file: 'zip error: File not found or no read permission'"
in the script output window
I believe this was a filename-encoding issue. I've had a go at
fixing it in CVS and the gretl snapshots. I haven't been able
to test on Windows yet myself, but I'd be interested to hear
if the snapshot works OK.
