PD Tweaker ... Anybody tried this?

Wondering if everybody has seen this, and what those with experience think of it...

Parallels Desktop Tweaker

 

Do a search in this forum. There have been several reports. The program does do what it advertises.

 

I tried it and didnt notice much difference, although I did notice my mac start to crash more after upgading to 10.4.7. I have no idea if the software was causing it, but I removed the software and my machine seems more stable.
