problem renaming/deleting files on other 'volumes' (OSX)

[Terry Judd]

I've run into a problem where I am frequently unable to rename or 
delete a file(s) on a volume other than my boot drive from within Rev - 
this is despite 'me' being the owner of the target files and folders. 
If I transfer the same files to my boot drive then all works as 
advertised.

Does anyone have any idea why I might be seeing this and if there is a 
remedy??

Rev 2.5, Mac OSX 10.3.8

Cheers,

Terry...
