Glenn, Thank you for your response, which confirms that the call to GetSaveFileName has repercussions (which, in my opinion, are undesirable).
I did try to get a directory listing after the call to GetSaveFileName (using perl and using backticks) and it seems to indicate that the current directory has not changed. Still, the backtick commands do not see the files in that directory unless I specify their full path. One thing I should try is to use ./filename instead of the full file path and see if that works. If so, that would be a decent workaround.
