If this is exactly the code you use, then the problem is in:

		else if ( target = OpenResFile( targetFile ) == -1 )

You forgot the extra pair of parenthesis, as in

		else if ((target = OpenResFile( targetFile )) == -1 )
	
What you were doing is calling OpenResFile() and testing if it was -1.  If
it was, target was set to 1 (true) and your routine started to do its thing
on what every resource file 1 was (maybe the System file).  Although I would
have expected that OpenresFile() to return a positive number, which doesn't
match -1, so target becomes 0 and your routine returns.
