Defraggler taking top thread priority

[JDub]

I understand this may be unavoidable but maybe a dev is unaware of it:

 

The relavants:

Dell E6410 - medium build (4gb)

Win 7 64-bit

Defraggler 2.03.282

Winamp 5.601

 

What happens is I'm listening to music and hit the analyze button it causes everything to stutter for .5-1.5 seconds on and off untill the analysis is complete. The mouse locks up too kind of skipping around. Same with the first part of the defrag process (building file list). It's the equivalent of a new driver not knowing how to work the brakes/gas pedal properly.

 

I have defraggler set to backround priority, I'm wondering if that only applies to the actual defragging process? It seems like something that *could* be made to work so that it doesnt cause the equivalent of harware interupts (remember that back in the day? opening your cd-rom could unfreeze your locked up machine)- Speaking of wich I could swear I heard a microsoft dev saying the new vista/7 kernel was re-written to avoid lockups and de-prioritize hardware interupts but it feels the same.
