Matt,

Thanks for sharing your thought to uncheck Speed Up Generation of Real Tracks. As I said in my original post I "Changed default setting to not allow faster generation of Fast Tracks".

My question -- is this a known problem on certain systems and/or configurations? So for example as per your idea that the problem is insufficient memory, is it known that Real Tracks will not work with 1 Gb ram on an XP system? Likewise, in regards manning's comment about Celeron, is it known that Real Tracks will not work with a fast Celeron processor?

Thanks for the tips re defrag. I will try them later tonight.

Jim
