Hi can I just clarify the powerpoint problem. Today I was uploading powerpoint presentations to our moodle site and I had a similar problem. When I clicked to see the presentation from within moodle something downloaded but I only saw a black page.
At one point I was asked if I wanted to open or save the file. Clicking open gave me the black page, while clicking save worked. This 'choice' is probably too much for my students to cope with!
If its the same prob I'll talk to the IT people and get office XP service pack 3 installed.
Thanks
Anne
