Thanks all. So far I have not been able to reproduce the problem, but what I
notice when checking the return status of LSCopyItemInfoForURL is I get
a paramErr (-50) for *almost* all files and folders in any directory. (The
other functions return no error). I'm not sure how to interpret that. It's
obviously not a parameter error since some files return noErr?
