  1. I can't reproduce that in the latest diff if we're talking about the Capture module progress bar. There is, however, a concurrency when using 1-second captures which causes the progress to remain at 100% while processing single-capture sequence jobs, but that's very elusive. With greater exposures I don't see the issue. If actually it shows up on lower-end computers I'll have a look, please tell me.
  2. Fixed
  3. I'll leave it like this, please tell me if you think otherwise. That construct has the advantage to bypass the management code for plurals :)

  Aha, let's have a look into this, thanks. I did actually check for this situation in a more general manner, that is, code should not presume of the order in which the scheduler jobs are sorted in the list, but I should have built a test vector.
