I have a C# window's app that uses the OpenFileDialog from a Linklabel onclick event.  When I run it on my PC the dialog box opens, however when other users run it, the dialog box does not open.  I'm running Window's 7 Ent Ed 64 bit, the other users are running same OS but 32 bit.  The platform in the app is set at x86.
 
Here's the code:
 
        public string GetFile()
        {
            string selectedfile;
            OpenFileDialog ofd = new OpenFileDialog();
            DialogResult dr = ofd.ShowDialog();
            if (dr == DialogResult.OK)
            {
                selectedfile = ofd.FileName;
            }
            else
            {
                selectedfile = null;
            }
            return selectedfile;
        }
 
Has anyone else has this experience?
