+Summary: Multithreaded App crashes in random locations
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+This app will not start up, and crashes in random locations. Not sure if
+it's a winforms problem or some race condition in the runtime as it always
+seems to die in a pinvoke.
+
+Steps to reproduce the problem:
+1. Run attached sample.
+2. 
+3. 
+
+Actual Results:
+Random exceptions 
+Stacktrace:
+

+ectangleF&,int&,int&) <0x00004>

+
+This application has requested the Runtime to terminate it in an unusual way.
+Please contact the application's support team for more information.
+
+Expected Results:
+No crash (like on .Net)
+
+How often does this happen? 
+Everytime.
