If I add a comment to a cell, it always seems to revert back to a set position, no matter how much I move it from the cell it refers to. The size remains as I've stretched it but the comments box always reverts to a position just off the top right of the cell.

Can this be changed so it stays where I drag it to??

Hi,
if you hide and redisplay a comment it will automatically return to the default position.
So a way around that is not to hide the comment and always showing it!

Good luck

There isn't really an appropriate place to have it showing all the time....although it might be a possibility if I rejig things slightly, thanks!

You're welcome.
You might be able to somehow trick the system though.
Since it is not possible to manually or programatically set the position of a comment if it hides and reappears you might be able to make a comment visible when a cell is selected and invisible when another one is selected with some VBA code.
But this might still not be 100% fool proof as a selection would make the comment reposition ones again!

Good luck
