Yes this is a problem. But you are also throwing out support for any other platform! I suggest you bring up these problems with VISA to your NI contacts. Feedback is important! The licensing fee for VISA is supposed to be small (we had a discussion about that here awhile ago). But the libraries can add a lot of size to an application! But then again, so does the LV runtime engine! -Scott
