getopenFile (in Perl Tk) has being failing more often in the last few days and has now stopped altogether.
In the Perl below I:
1. can see the GUI
2. can use the button and it appears to go in and out
3. can see the content of the print statement
but then nothing happens and all I can see is a small 'waiting' circle which seems to rotate.
I replaced my version of Perl by one from another laptop where the test perl works. Sadly it still failed.
The troublesome laptop is using Windows 8.1, the 'good' laptop is using Windows 7 Home Premium.
I do not know if it related but also I cannot save documents in either Word or Excel.
Any clues as to what is wrong and it can be cured would be much appreciated!

use strict "vars";
use Tk;

my ($mw);

    sub org_select {

    my $filetypes =     [
            ['Drawing Files',    '.drg'],
            ['All files',    '*']
            ];

    print "\nbefore getOpenFile\n";

    my $select_file_full = $mw->getOpenFile(
                    -filetypes  => $filetypes);
    }

$mw = MainWindow->new;
$mw->Button(-text => 'Select File', -command => \&org_select )->pack;

MainLoop;
