Julian, I guess you mean AG 3.2? Perhaps you have a different bridge issue than the one that was fixed a year ago. That problem was due to a change in some distros to python2.6. Fedora 10 used python2.5 so your problem must be something else. In any case, the latest F10 release, AccessGrid-3.2-4.fc10.noarch.rpm, already contains the fix. Sorry - that doesn't actually help you - unless some of your VenueClient machines are using different versions? chris > > JULIAN CASTRO MAYORGA > ING.
