[IronPython] Importing standard Python libs

Hmm, but this is strange.

The Interop works, but IronPython throws a lot of exceptions
at me when executing, or rather, passing a string to execute
as a function, for example, in the remote application.

Here's the exception:

************** Exception Text **************
System.Runtime.InteropServices.COMException (0x80040201): An event was 
unable to invoke any of the subscribers (Exception from HRESULT: 0x80040201)
errorCode, IntPtr errorInfo)
hresult, ExcepInfo& excepInfo, UInt32 argErr, String message)
    at CallSite.Target(Closure , CallSite , Object , String )
site, T0 arg0, T1 arg1)
    at CallSite.Target(Closure , CallSite , Object , String )
    at CallSite.Target(Closure , CallSite , CodeContext , Object , String )
site, T0 arg0, T1 arg1, T2 arg2)
    at onBtnPressed$101(Closure , PythonFunction , Object , Object , 
Object )
function, Object arg0, Object arg1, Object arg2)
    at IronPython.Runtime.PythonFunction.FunctionCaller`3.Call3(CallSite 
site, CodeContext context, Object func, T0 arg0, T1 arg1, T2 arg2)
    at CallSite.Target(Closure , CallSite , Object , Object , EventArgs )
site, T0 arg0, T1 arg1, T2 arg2)
    at _Scripting_(Object[] , Object , EventArgs )
    at System.Windows.Forms.Control.OnClick(EventArgs e)
    at System.Windows.Forms.Button.WndProc(Message& m)
    at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
    at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 
msg, IntPtr wparam, IntPtr lparam)

the code that I execute is simple, it looks like this:

maxApp = 


maxApp.runMXS(r'colorMan.getColor #background')

this is a call to a function of the remote app (colorMan) and
its method for getting the app's color.

The weirdest thing is, some functions, even though they
throw an error, still get executed after I hit "Continue".

Do you have any idea what might be causing this?

Thanks a lot in advance, cheers,
