Resizing Pictures in Cell Tables Hit or Miss

[MikeWhite]

Cannot figure out why in some situations it works and some situations it does not work, but let's say I have a 2x3 Table and I want to put 6 pictures in it, with each picture being 2" wide. Most of the time when I paste (I usually paste as most of the time they are screenshots) the picture in the cell, then go to the Format Tab and then either manually type in 2 or move the sizing arrows to 2 everything is fine. But every once in a while, the size box will not let me enter the width, nor resize with the arrows. I am using Microsoft 2010. Thank you. Mike
