I've run into a SalesLogix WEB issue a few times now, particularly after an upgrade, and it can be frustrating.

Here's the problem, you click on the group, for example your "Customers" group, and it does not actually show your customers; it still shows "All Accounts" or whatever you were last viewing. In addition to this, if you were to look-up an Account while in this group that is not properly working, you'd return nothing. In fact, it wouldn't even give you a proper field to look-up on. How about the filters on the right-hand side? Not a chance these will work for the broken group either!

So, on to the possible solutions: If you have recently upgraded SalesLogix from an older version, there may be two versions of the system groups (All Accounts, My Accounts, Customers, Etc...). One is newer and works, but the old one will not, and this will cause this issue. As the SalesLogix Administrator, you can login to the Architect, find the incorrect one and delete it. This will fix the issue for everyone. As a user, you can always copy the group and hide the one that is not working, but I'd definitely try to get your Administrator involved to resolve the issue for everyone in one shot.

I have seen this issue caused by an out of date browser as well. Make sure you are running IE7 or newer if the problem continues after the Administrator clears things up.
