[imp] Possible bug in Zip download function in IMP

[P.V.Anthony]

Hi,

I seem to notice a problem with the zip download feature in IMP for
attachments.

When I unzip the file using 7zip from http://www.7zip.org, it says that
the file is not supported. When I unzip the file using WinZip it works
great.

Next I compressed the files using WinZip then uncompressed it using 7zip 
and that works great.

I am not a programmer so I am just assuming that maybe zipping class in 
IMP may have a small bug.

I was hoping to use 7zip as it is a great app plus it is free.

Any advise is much appreciated.
