I would like to read a resource out of the Desktop file.
Unfortunately, under multifinder it is always open and OpenResFile
always returns error -49.  (This is not a problem if I do this in an
application without MF.)  I know the file can be read by other means
(MPW can duplicate the Desktop file while Finder has it open, for
example) and there is some discussion in IM4 about how to refer to an
open file for "regular" file I/O.

Question: if I want to be able to read the resource at any time, must
I thus write code to read the resource fork and manually locate and
read the resource, simulating what GetResource et al do?  I note by
the way that ResEdit doesn't attempt to solve this problem.

	Thanks / JBL
