I am running OS10.5 with VDL 2.5 and Sibelius 4.1  and I cannot get the Template to ";Save As";  I am a bit of a newbie, but it was working on my 10.3,VDL 2, Sib.4.1 machine.  Once I upgraded and switched OS... no more saving.  Any thoughts?

Thanks Jim,
That did the trick.

According to Sibelius, saving files in Sibelius 4 doesn't work if you're using Leopard, but they have a small compatibility update that should fix this up for you.
