[IronPython] Still stuck on rich editor with IronPython and Silverlight

[Jimmy Schementi]

Michael, let's get Dino in on this ...

Dino, This seems like our fault, but I'm not savvy enough to track it down or verify my claim. Seems like it doesn't work regardless of invoking via reflection or ref.emit code; calling it's constructor 10,000 times still gave the same result. As Michael said, doing anything with RichTextBox fails when invoked from IronPython, but works fine when invoked without IronPython on the stack (pure C# app, for example). I'm amazed that it fails when *called* from C#, meaning that IronPython is doing something to make statically compiled code fail. 

We can look at this together on Monday unless you get to it sooner; I thought I knew how to use windbg but failed miserably at doing anything useful, so you'll have to help :)
