title: Winforms SplitContainer always displaying split cursor
body: <p>I'm new to winForms, I'm trying just to create a simple SplitPanel.
  I just drag it from the tools.</p>
  <p>The problem is that if I move the mouse over the panel, the cursor shows the &quot;split cursor&quot;, even if it is not over the split divise or even if I add some controls inside it.</p>
  <p>I can't figure why and can't find nothing related to this (I don't attached a printscreen cause it hides the mouse and the problem is simple to explain)
  Can this be a framework problem?</p>
