From an XP Pro SP2 notebook with JRE_1.5.0_02 I use unified magager without problem on BCM 3.6 and BCM 3.7. On the contrary on 3.0 some combo controls don't work. I change the parameter (for istance the net link manager from enable to disable) but if I exit the page and come back to the same control nothing is changed. It doesn't happen to all the controls.
