Hi Edwin,
Thanks for the tip. I'm going to try it now and keep you informed
about the results.
Still, my questions remain.
When I wrote that an 'Information' window appears informing 'Download
complete' that doesn't mean that the download was successful. In fact,
the download didn't occur but that particular window appears. Why?
The other two questions aren't answered yet:
why is 'winzip70.exe' referred as 'Down72d063a0'?
In the 'Save As' window, why is the file referred as '.Document' type?
This is becoming a red flag situation.
