Re: Zip Files are Blocked


I'm also experiencing this. The wonderful thing is, there is NO UNBLOCK
BUTTON on the properties dialog!

There was another suggestion in the forum here that involved the policies
editor which I am going to attempt. The settings in the policies editor for
attachment manager are all 'not configured'. I suppose I need to do a reboot
for any changes to take effect (making then disabled), so I will see what
happens after doing so.

If it matters, the .zip file I am opening was generated on a Win CE device,
using the zlib zip code, and it opens just fine with WinZip.....

The big question is (and I've seen this on more than one XP/SP2 machine
today)..
Why would I be getting the 'blocked' warning and no unblock button in
properties?
