using shift/alt modifier with numpad keys

[colin]

It seems windows loses the numpad information if you have num lock on and
press <alt>+numpad6
is there any way round this with .net ?

I realy need all the numpad keys to be used to move and rotate
one of several objects in 3d,
with alt/shift/ctrol used to determine wich object
eg model/camera/surface/wire/node etc...
