folder creation anomaly on Mac Mountain Lion?


I’ve recently made the jump from PC to Mac after many years of running Nuendo in a PC environment.

Since the switch I keep on coming up against this small but rather annoying anomaly. When I create a new project & select an existing folder within my Documents location on my Mac & create a new song project folder within that folder - the resultant folder always ends up outside of that selected folder in the main list within Documents. Does that make sense? What am I missing here? I always end up having to drag the new project folder back into the main aritist folder I’ve created to contain all the separate song projects within. A bit frustrating - can anybody set me right please?

with thanks,
