Should there be a delay when doing copy and paste in excel?
Normally, you should not experience too much of a delay.
Sometimes exiting all applications and rebooting your computer,
then going back into the application after the computer has started
again will solve the delayed-response problem experienced by some
Windows computers.
Some other causes for a delay could be a spreadsheet that is
very large and complicated, or a computer that is low on memory.
Increasing RAM in a computer is the best way to increase a
computer's speed. If you already have 3 GB or RAM (maximum
accessable by Windows XP), then you might need a faster computer to
increase performance.
