... Also, when I make changes in the orignal worksheet, the same
changes take place in the second worksheet as well.

From the above lines, I guessed OP's file had 2 windows opened and
apparently the same sheet (the "original" worksheet) was simultaneously tiled
on-screen. That could explain why the changes he effected on one tile showed
up immediately on the other. Just my take on the post.
