MessageBox oddity

[Earl]

Relatively new to C# and I have an odd situation. When I show a messagebox
when catching an exception, the message shows briefly then disappears.

private void PopulateBrands()
{
SqlConnection strSQLServer = new SqlConnection(strConn);
SqlCommand cmd = new SqlCommand("sel_BrandsEST", strSQLServer);
cmd.CommandType = CommandType.StoredProcedure;
if (ds.Tables.Contains("dtBrands"))
{
ds.Tables["dtBrands"].Clear();
}
try
{
strSQLServer.Open();
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cmd;
da.Fill(ds, "dtBrands");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
dtBrands = ds.Tables["dtBrands"];

}

In the debugger or in the release version? All sorts of strange things can
get intercepted by the debugger.

In the IDE. Strange, the equivalent syntax in VB.Net does not do the same
thing.

Is this happening in a non-UI thread?
Ie. What is calling this method?
