Don't ever call control methods and set properties from a thread different

called, but as a rule of thumb don't do that. When you want to access
control form worker thread use Control.Invoke to marshal the code. In order
to find out where is ssafe to call a method or set a property you can use
Control's IsInvoleRequired property.
