S&D offers to clean temporary files upon start up and I always say yes.

Question 1: sometimes it says there are 800 or more temp files. Does this mean there is something suspicious going on? Is a very high number of temp files normal even though no programs are currently open other than S&D?

Question 2: then when it's done cleaning out the temp files it reports are many could not be cleaned. Is that normal also when there are no programs open?

thanks,
