```
TaskEditDialog ted = new TaskEditDialog(dct, true, true);
try
{
ted.ShowDialog();
```
On Windows 2008 R2 Server, logged in as an Administrator, when the ShowDialog() call exits (but before it hits the next line of my code) I am seeing an Unhandled Exception.
On my Windows 10 dev machine it is absolutely fine, on other platforms it also seems fine. It is the specific circumstances that seems to be causing the problem.
Any advice most welcomed. If I can provide more/better diagnostic information I'd be very happy to.

That is a very strange error. From the trace, it appears that on close, the combo box at the bottom of the form that selects compatibility is having an internal message pump problem. The handler is the native .NET combo box. I'll check my code on how I'm handling close events on the subclass I created. I created a very simple 4.5.2 app with the 2.5.22 NuGet packages and don't see the same failure.
