When I try to merge a 45 thought brain into a 1700 thought brain, the status bar displays halfway, then hangs. PB CPU activity is zero to minimal (1-2%). The same thing happens if I do a copy selected thoughts in one brain and try to copy them into another. I was able to make a "smaller" copy work from another brain to the same target. I cancel the PB process after half hour to hour wait. Any thoughts? I haven't spent the time (yet) testing out other merges and copies.
