I was wondering if anyone could help.

Part way through designing my site using web designer 6. Each time I go to save the document (File > Save) or (File > Save As) I receive an error message; failed to copy XAR files and the document doesn't save.

If I give the document another name, then it saves. So far Im up to copy 5... but it won't simply save the document I already have open under its existing name, i.e. update it to its newest version.

Can anyone tell me what XAR files are and why there might be a problem and how to overcome it?

Thanks...
