@mcored: Add this line to ShareXmod Program.cs:
https://dl.dropbox.com/u/14076298/ShareX/2013/04/Xs6hhmCLDx.png

i told you in commit comments before.

Thanks Berk; however, I did not think it was necessary to do the 
null/isDisposed check because in my get property for MainForm I do check it: 

        public static MainForm Main
        {
            get
            {
                if (_MainForm == null || _MainForm.IsDisposed)
                    _MainForm = new MainForm() { Icon = Resources.ShareX };

                return _MainForm;
            }
            set
            {
                _MainForm = value;
            }
        }

It is strange.

madLyfe, try this: 
https://dl.dropbox.com/u/25501373/ShareXmod/2013-04/27/ShareXmod-7.2.3.348-setup
.exe

It should not happen again. If it does, please let us know!
