Here's a small Q about the noise reductioin HUD in Soundtrack Pro: When I'm working with the NR HUD and click off STP into another app, say Skype, then come back to STP, the NR HUD is gone with all my tweaks..!? I have to open a fresh NR.. Is there a way to keep the NR HUD up or get it back after I switch apps for a quick sec? This happens to me constantly and is a little frustrating..to say the least! thanks -Adam.

this is actually happening to all the effects HUDs as well..

Yes, once the filter controls are open, you have to Apply it or save as a preset before moving out of the app. There are several bugs in STP that Apple never got around to fixing.
