jit.matrix importmovie -- remote urls on windows

Hi there --

I have a cross platform application Im working on in Max 5, on OSX 10.6 and Windows XP.

On the Mac, Ive frequently loaded image data into matrices from a local or remote server. I simply use a "importmovie http://localhost..." message to jit.matrix, both in javascript and in the patcher. Never any trouble with performance.

However, on windows, this function does not work. While I can see from the server logs that the remote source is indeed queried promptly, Max itself basically freezes for several minutes before either crashing entirely or recovering without actually loading the image.

I havent found any documentation on using this message with remote urls, nor any mention in the forums. Is this is a supported feature? Is there something I can do to make it work on windows?

thanks ---
