Exceptions are ignored in x64 form_load

When I throw an exception from form_load in my C # app, it doesn't work when platform is x64. (it acts as expected for x86)

When I step through the code, I end up on the line where the exception is being thrown and then immediately jump to timer_Tick.

When I create a new project and add this line to form_load: throw new System.Exception ("oops!");

In case of x86, it crashes. For x64, it doesn't crash.

Is there any way to get the application to actually eject from the form_load on 64-bit?
