title: Set property 'System.Windows.FrameworkElement.Height' threw an exception
body: <p>An in-house application coded in C# and WPF works without incident for 20+ people except one user. The first window displayed usually (but not always) results in an exception that our exception handler diligently reports:</p>
  
  <pre><code>Exception trace:
  Set property 'System.Windows.FrameworkElement.Height' threw an exception.
  Overflow or underflow in the arithmetic operation.

  <p>There's no obvious problem with the XAML, and I'm never directly touching the height of any element. I've tried making the window default to a larger or smaller size, but that hasn't resolved anything. It's actually a simple user log in window. The problem often but not always goes away after goes away on reboot.</p>
  
  <p>I don't expect a silver bullet to this problem, but it's not clear where I should begin in debugging -- WPF seems to have a design flaw that makes it nearly impossible to debug such exceptions?</p>
