I can not download any songs from the Scriptorium. All I get is a blank page with a little box with a red X in the box. Box is located in the upper left hand corner of the page. I remember downloading before, but can not do it now.
Try clicking with the right mouse button on the composition you want and then select "save target as". Then choose the folder for the composition to be saved in.
I think the problem you may be having is Internet Explorer. It no longer supports the NWC plug-in's. ((Unfortunately, that also seems to mean that one can not right click the little "x" in the upper left hand box and get the option to "save as".
The solution: use an alternate browser to access the Scriptorium. Netscape, Opera and Mozilla all work just peachy with the Noteworthy plug-in.
