Stuck with ILIDE

Question

I'm trying desperately to find a (good, even any?) IDE for MSIL. (For that c : http://stackoverflow.com/questions/640583/ide-for-msil)

I thought I found one with ILIDE, but when debugging my code I always (it's not depending on the code) get :

SandDock]TD.SandDock.ControlLayoutSystem::OnMouseMove(System.Windows.Forms.MouseEventArgs

When I don't use the mouse (since it's apparently triggered by e mouse-over) I get :

System.NullReferenceException from 'debugger 3' without any additional info.

Anyone used the program (3.0) with more succes?
