Vista - Not possible to make shortcut to filename.scr with switches?

I have been programming a screensaver, and I have made an installer for it
which makes some shortcuts in the start menu.

But I have found a problem, and it doesnt make sense, and I have no idea
what to do about it:

When I try to make a shortcut to "filename.scr /c", and then run it, windows
switches the /c with a /S. which means the screensaver will start, instead of
showing its configuration.

Any idea of what to do about that??

I could make a batchfile or something, but I feel that would just be
cheating and not a real fix...
