If an interface pointer is assigned to a variable it cannot then be used.

Example:

This works fine

'itgm2' Œwi 'New' ('itg' Œwi 'interface')

This doesn't

ttt„('itg' Œwi 'interface')
'itgm2' Œwi 'New' (Œfirst ttt)

and gives a ŒWI CREATION ERROR: Invalid object pointer

Same thing happens with EnumNext.

Watch out for how you're using it. If that code is in a function and runs straight through, then it'll probably work. But if you're doing it in the session, or if you put a stop on your function, then the pointer will get invalidated when execution stops between the lines and you won't be able to continue.

([]first shouldn't be needed either.)
