Problems saving documents with Amaya 9.5.3

I use Amaya 9.5.3 for MacOSX 10.4.8 for PowerPC.

I have a recurring problem. I am able to open files, and edit them  
with ease. However, when it comes time to save the file, using the  
Save command, I receive all sorts of error messages, including

File not found (for the W3C Member homepage)

Cannot Save in (foo.uri)

I then have to go back to "Save As", which sometimes triggers a full  
dialogue box, sometimes triggers a box with only the uri and the mime  
type, and sometimes just puts me in the loop of "Document Changed,  
save?" then "Redirected to ..." in a loop.

If you can provide some help  here, I would appreciate it.

Many thanks,

Janet
