Group's of contacts explode after being sent

[Eli]

We are slowly upgrading everyone in our office from XP/Office 2003 to Win7/Office 2010. Out of the 8 people we've upgraded so far, 2 of them have the following issue; When they are creating an email and click To-> and add a group from the contacts list, after sending the email the group explodes and shows all of the contacts without initially expanding it.

Our server is running 6.0.7 and the new computers are running ZCO 7.0 up from 5 and 6 previously. All of the computers are configured and setup exactly the same. So why do 6 work and the other 2 don't? This sounds like a ZCO issue, but it could be something else.

You are asking for problems if you run a 6.0.7 server with a 7.0 ZCO. It may work, but there could be issues. The reason for this is that ZCO may have newer features that haven't been implemented in the server yet.

The supported configuration is to have ZCO version either the same or older than the server version.

Are you not able to upgrade your server? If not, what happens if you run 6.0.7 ZCO versions? If there is still a problem, then we have an issue.

Putting the ZCO back to 6.0.7, the same as the server fixed this issue, thanks!

I bumped the other person back to the 6.0.7 ZCO and they are still having trouble with they're groups automatically expanding. It worked for one, but not the other.
