+Summary: ListView horizontal scroll issue in details view
+Description of Problem:
+When a ListView in details view is resized to a smaller width, the 
+horizontal scrollbar appears even if there is no need for it.
+Steps to reproduce the problem:
+Compile and run the following program.
+using System.Windows.Forms;
+class TestForm : Form {
+    static void Main() {
+        Application.Run(new TestForm());
+    }
+    public TestForm() {
+        ListView l = new ListView();
+        l.View = View.Details;
+        l.Columns.Add("");
+        l.Items.Add("");
+        Controls.Add(l);
+        l.Width *= 2;
+        l.Width /= 2;
+    }
+Actual Results:
+The horizontal scrollbar.
+Expected Results:
+No scrollbar.
+How often does this happen? 
+Always (on the SVN version).
+Additional Information:
+I'm not sure I understand the layout logic of this implementation, but the 
+problem seems to be in LayoutDetails.
+I suggest changing
+layout_wd = Math.Max (header_control.Width, item_control.Width);
+layout_wd = header_control.Width;
