I think the single dong sound on the desktop windows 7 mustbe the presence of skyple, but not sure, it also says I am now more than 16 days over due, I do not buy on line use the calanders,a sighted visitor said it seems to be an invitation Jaws did not speek that,but a sighted person could read it, I told her not to delete it untill I can find out more about it,it does not say that on this laptop which would have received identical information,so rather strange .Incidentally can anyone explain the make up of an mp3 file? the skype tutorials are mp3 but the lady giving the tutorials,uses partof the time I imagine Jaws speech engine? and at a fearful speed can a mp 3 file be slowed down if only partof it is burbled? thanks
