Hi guys,
This is stack trace I got:

Exception = System.Runtime.InteropServices.SEHException
Message = External component has thrown an exception.
FullText = System.Runtime.InteropServices.SEHException: External component has thrown an exception.
   at MySQL.Forms.DrawBoxImpl.drawbox_mouse_click(Object sender, MouseEventArgs e)
   at System.Windows.Forms.Control.OnMouseClick(MouseEventArgs e)
   at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks)
   at System.Windows.Forms.Control.WndProc(Message& m)
   at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)
   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

How to repeat:
1) Create a database connection
2) Create a new server instance
3) Select "Manage import / export" or "Manage security"
4) Choose the newly created server instance
5) Click Ok and bang...

Suggested fix:

Q: The server are you trying to connect it is a remote or local?. Thanks in

A: I have tried with a local one (localhost) and a remote one (noitso-udvik). The remote server is on the same domain as the calling server. Firewalls are disabled. I can connect to both servers and execute queries on both. It only fails when I try to do the before mentioned flow.
