Well as usual I can't find a simple explaination.
Apparently there is more to it than this, unfortuntely. It acts like there is a lack of assocation with an application and it doesn't know what to launch when you execute the .scr.
This is not specific to MA and so the renaming didn't help. But it was a good suggestion.
I found this in the MS knowledge base and I thought this would solve it (although it is for NT an I am on w2k) but no joy.

Appreciate the input, I guess I will just have to be "shortcutless".
