DataBinding using Strongly Typed Datasets. Binding to a DateTimePicker and Combobox - Focus on Leave bug

When using a strongly typed dataset (generated from the Visual Studio IDE
from an XSD file) and databinding I get a really odd error when binding to
both a combox and a datetimepicker.

I bind like the following:

//// tDs is the strongly typed dataset,
//// tDs.TheTask returns a strongly typed row from one of the tables.
/// GetBindingTaskTypes() returns the types I want to use as a datasource in
an arraylist.

dtPicker.DataBindings.Add("Value", tDs.TheTask, "TaskStart");

cBox.DisplayMember = "TypeName";
cBox.ValueMember = "TypeID";
cBox.DataSource = tDs.GetBindingTaskTypes();
cBox.DataBindings.Add("SelectedValue", tDs.TheTask, "TaskType");

The problem occurs when presented with the user interface, once the value in
the cBox is changed and the focus is moved elsewhere the cBox steals the
focus back! Now usually it just steals it back once.
However it refuses to move focus to any control on a different groupbox or
tabpage and then proceeds to hang so that you cant even close the form down.

Does anybody know anything about this kind of behaviour?

Kind Regards
