Last night I installed on two of our systems the BCM.R400.SU.Desktop.012 and BCM.R400.SU.System.017 patches which were released by Nortel on December 15th. After installing these the "Get New Updates..." and the "Add..." buttons under the Software Updates section no longer bring up the pop-up screen that allows you to enter the download information. When you click the buttons you get the hour glass for a second or two and then nothing happens. I scheduled the software downloads on one of the two systems so both of the patches were applied. The other system however I updated manually with the SU.System patch first however when I then wanted to install the SU.Desktop patch I could not. Both systems have the same issue. Other BCMs that have not yet been updated are fine. I tried re-installing the new cartriges, rebooting the PC to no avail. Anyone else experiencing this? Any suggestions?
