[users] Calc - missing Help files

[John Barman]

I have been following the post on the above subject with interest, not 
realising I too was a victim.
I have tried to pick out the  solution fom the discussions, and have downloaded 
the four substitute files. Three of them downloaded OK and they have been 
installed. the fourth file 'scalc.jar' persists in downloading  as 'scalc.zip' 
(with 300 files in it!) .I have made 3 attempts now but always with the same 
result! What is going on here?
