COM IDispatch and Powershell invocation

Can Powershell handle COM invocation with Object implementing Idispatch
interfaces. I would think so, however why can I run a piece of script via the
VBS engine while Powershell failes. Please help!

*********Powershell*********

$b = New-Object -ComObject Station.Application
$b | gm
$b.connect("")



TypeName: System.__ComObject

Name MemberType Definition
---- ---------- ----------
CreateObjRef Method System.Runtime.Remoting.ObjRef
CreateOb...
Equals Method System.Boolean Equals(Object obj)
GetHashCode Method System.Int32 GetHashCode()
GetLifetimeService Method System.Object GetLifetimeService()
GetType Method System.Type GetType()
InitializeLifetimeService Method System.Object InitializeLifetimeService()
ToString Method System.String ToString()

Method invocation failed because [System.__ComObject] doesn't contain a method
named 'connect'.
At line:1 char:11
+ $b.connect( <<<< "")


*********VBS*********

However, this seems to work.

dim myStation
set myStation = createobject("Station.Application")
myStation.connect("")


Any idea's about the difference? It's my understanding the PowerShell can
handle Idispatch interface for late-bind of COM object. So why doesn't this
work?

Does late-binding works?

[system.__comobject]::invokemember("connect","[system.reflection.bindingflags]::invokemethod,$null,$b,$null)
