I am using GF 1.3.12 with WP 3.0 with network configured.
With GF network activated, there is a significant delay opening the various plugin panels (Recently Active, Inactive, etc.) and the yellow "There is a new version of ..." upgrade notice disappears in that subpanel.
When I deactivate GF 1.3.12, the delay disappears and the notice reappears.
I've tried various combinations with other plugins, and I haven't been able to find any other conflicts.
Does anyone have suggestions as to how I might be able to discover more about this GF conflict?
