Not with Print, but you might be interested in the new version 6 function, PrintTemporary, which prints cells that go away when evaluation is completed. This would make the clutter only tempmorary. > As a side note, trying to solve this (minor) problem, I happened to > find: > > ProgressIndicator[Dynamic[x]] > > something which seemed perfect! > Yet, I'm still unable to use it: for some reasons it is not updated > <until> the calculation (which requires the progress indicator) is > finished. At that point, useless, the bar moves from zero to full (and > yes, dynamic updating is enabled) My guess is that you've made ProgressIndicator part of the output, in which case you won't see it until the output is sent to the FE. You need something which produces an immediate side effect rather than a final output, which is exactly what Print and PrintTemporary do. For example...
