microsoft.public.windowsxp.help_and_support

In the past I have saved documents to CD-R but yesterday I got a message
"Windows encountered a problem when trying tocopy this file. What do you
want Windows to do? Retry/Cancel"
I have successfully copied the file and saved it on the hard drive so it
seems to be a problem with the CD drive. Anyone got any ideas, please?
Coincidentally (or maybe not) the right click on my wireless mouse has also
ceased to function!
Any help greatly appreciated.
