Software and driver problems

For some programs, dates cannot be sorted in correct order
Solution: Some programs developed before the year 2000 use only the last two digits of a year to sort dates,
assuming the first two digits are 19. Consequently, dates cannot be sorted in correct order nowadays.
Check with your software manufacturer to see if any updates are available. Many software manufacturers
make updates available from the World Wide Web.

Solutions:
