4.06 almost perfect
 

Used 4.06, ran for 7 hours. The only problem I had was with the search function. The graphics of the search window was slow to catch up with only part of the window showing up. You cannot search while a song is loading either.

Songs load faster that on other 4.X versions but not as fast as 3.X versions.

All background programs shut off. Both displays set to 1024x 768.

I give it 8 out of 10 stars.
