I have a Perl script which creates/edits a Word document and then makes it visible for manual editing and possible printing. When the editing/printing has been done, the user closes the document and the Perl script detects this and continues with additional tasks. The code I use to detect that the document has been closed is as follows: 
$mydoc = $word->Documents->Open($xfile);
$mydocnt = $word->Documents->Count();
while (($mycnt = $word->Documents->Count()) == $mydocnt) {
    sleep 5;
}

This mostly works fine but if the user closes Word rather than simply closing the file the above code produces an error which causes the Perl script to exit. The error messages say '"The RPC server is unavailable" in METHOD/PROPERTYGET "Documents"' and 'Can't call method "Count" on an undefined value' although the exact error messages are irrelevant for purposes of my question. The question is either: 1) How to detect when a document has been closed which also works if Word is closed instead? or 2) How do I prevent the obnoxious messages from terminating the Perl script?
