Hi, I experience a hang when I try to drag more than 12 modified/added files into a different changelist. The hang happens less than one second after the files are dropped into the destination changelist. The hang only happens when the number of files is 13 or more. It doesn't happen when I try to move 12 or fewer files. The hang also happens when I'm dragging >=13 files between changelists. The app does not hang if I use the 'Move To Change Set...' command to move files to other changelists. When the hang happens I get the OS X 'spinning beachball' icon and I have Force Quit the app to continue. Has anyone seen this before?
