Hi everybody! I'm the maintainer of video.module . We have realeased a good 4.6 video.module then the past weeks worked hard for the new 4.7 version (MAIN). Now we have a patch for a bug in the 4.6 branch but I'm not able to submit it to the 4.6 branch I tried it but not luky with cvs... I'm getting: cvs commit: sticky tag `DRUPAL-4-6' for file `video.module' is not a branch Does someone could explain how can I do it? Thanks Fabio
