There's a good chance the student's browser has been hijacked by spyware/adware, particularly assuming that they are using the infamous combination of Windows and Internet Explorer.

Spyware and Adware often do things like changing your homepage and search links to the address of porn sites and although I've not heard of this exact behaviour it does fit their general behaviour.

I'd suggest running Spybot and adaware on the machine to clear anything out.

To prevent these kinds of things happening again I'd recommend that the student use Windows Update regularly and switch to using the FireFox browser.

1) I believe you can set the sample rate for the 'project' and it will automatically convert any audio files in the project to that sample rate

2) The audio can be 'up-sampled' as well as 'down-sampled' which means any source can be put on CD but bear in mind that any quality lost by down-sampling (primarily in the higher frequencies) will not be regained.

3) 44.1Khz is the standard for CDs and many other applications. It's a bit of an odd number (based on the range of human hearing and the width of video tape I believe) so many people round it off for ease.

4) Don't know

I'm not sure what you're using to create the files but many programs will automatically reduce the sample rate (Hz) as the bitrate (bps) gets lower.

Originally it was stated that 44.1kHz sample rate was needed for the flash player to work, but I think Martin later mentioned that 22 or 11 would work too.

If you can't find a classname in the styles.php file then that probably means that there are no styles set for it. You can add one yourself though by copying the syntax used for other classes e.g.:

.activityresource {
    border: thin dotted red;
}

I'm not clear on whether you also have Moodle installed at home or it just works when accessed via a browser from your home machine but:

The HTML editor doesn't work with the Safari browser, so that may be the problem. Try accessing it with Firefox or Mozilla on the Mac.
